Area of a Square
The area of a square is given by the formula: Width × Height

For example…………

Calculating the Area of a Square

The area of a square can be found by multiplying the base times itself. This is similar to the area of a rectangle but the base is the same length as the height.
If a square has a base of length 6 inches its area is 6 6=36 square inches
Calculating the Area of a compound shape

Calculating the area of a compound shape is the same as calculating the area of an ordinary shape. For example with this shape you can see its made out of two shapes therefore you can separate them into two squares like this. Then you work it out using the same formulas in both squares and then adding the two numbers up , remembering to add the cm2 at the end of it.

Common mistakes made:
All length and heights are added rather then width height, calculating the perimeter instead.

Area of a Circle
The area of a circle is given by the formula:
Area of circle= π×7×7=

For example…………
7cm

Calculating the Area of a compound shape

0.75 × 0.75 = 56.25
0.75 ÷ 2= 0.375 R= 0.375 π × 0.375 × 0.375 = 0.441776466
0.441776466 ÷ 2= 0.220893233
0.220893233 + 0.5625 = 0.78328125m₂
Area = 0.78328125m₂

Area = 0.220803233

Area = 0.5625

0.75m cm

0.75m cm

Common mistakes made:
Forget to divide the answer by 2 when calculating the area of a semi circle as we are trying to calculate the area of a semi circle and not a circle.

Area of a Rectangle
The area of a square is given by the formula: Width × Height

For example…………

Calculating the Area of a Rectangle

How to find the area of a square:
The area of a rectangle can be found by multiplying the width by height. This is similar to the area of a square but the base is not timed by itself.

Calculating the Area of a compound shape

Calculating the area of a compound shape is the same as calculating the area of an ordinary rectangle. For example with this shape you can see it’s made out of two shapes therefore you can separate them into two rectangles like this. Then you work it out using the same formulas in both rectangles and then adding the two numbers up, remembering to add the cm2 at the end of it.

Common mistakes made:
All length and heights are added rather then width × height, calculating the perimeter instead.

Area of a Triangle
The area of a square is given by the formula: multiply the base by the height, and then divide by 2

9 × 6= 54 Area =27cm2

For example…………

Calculating the Area of a compound shape

Calculating the area of a compound shape is the same as calculating the area of an ordinary triangle. For example with this shape you can see it’s made out of three triangles therefore you can separate them into two triangles like this. Then you work it out using the same formulas in all the triangles and then add the three answers up, remembering to add the cm2 at the end of it.

Common mistakes made:
Remember to divide the answer by 2 after multiplying width and height to calculate the area of a triangle.

1cm

2cm

Area of a Parallelogram
The area of parallelogram is given where b is the base length, h is the height.2cm

Area of a Trapezium
The area of a trapezium is given where
A = ½ (a+b)h where a and b are the side Lengths of the parallel sides, h is the height

Area of a Rhombus
The area of a rhombus is given where A = ½ a× b where a and b are the lengths of the diagonals

Area of a kite The area of a kite is given where A = ½ a× b where a and b are the lengths of the diagonals

Hypothesis

...How surface area affects the rate of diffusion. Hypothesis – the larger the surface area the faster the rate of reaction Why did you choose your hypothesis? The reason I have chosen my hypothesis is because large surface area of the tea bag will contain more molecules which means the rate of reaction will happen faster. For example the pyramid due to it 3D shape provides more sides for diffusion to take place and more area in the middle for the tea molecules to move around which will make them escape quicker so the reaction will happen faster. 2 web sites I have done my research, a) http://www.mylearning.org/learning/investigate/Tea%20Bag%20Trials.pdf b) http://www.science-sparks.com/2012/01/02/get-the-kids-to-make-your-cuppa-investigating-teabags/ I prefer website science-sparks because I found it easier to follow and also it was more useful was because it’s a scientific website therefore it was more accurate than mylearing. It also appeared to make more sense to me. Therefore website science-sparks was more detailed and had a diagram whereas website mylearning didn’t have one so it was hard to understand how to do the experiment and how to set it all up.

Pyramid Mummification

...Have you ever wondered how the Great Pyramids of Giza were built? Or how the Egyptians mummified the dead? Or, even simpler, how they lived their daily lives? Well, according to David Macaulay in the book Pyramid, life was fairly simple. Most Egyptians were farmers. Since the Nile flooded for a time from July to November, farmers were drafted for pyramid building since farming was impossible. Pyramids were constructed for a pharaoh so that when he dies, he is mummified and put into a sarcophagus inside the pyramid along with everything else that belonged to him including is pets, servants, and possibly even his wife. But in order for a pharaoh to get his desired afterlife, he has to go through a series of mummification steps. Most...

Ziggurat Research Paper

...the ziggurats staircase. • This temple sits on top of the famous Anu Ziggurat. • This particular temple was for the sky god “Anu”. • The temple was entirely white washed as it shining in the sunlight, making it almost impossible to pass by. • Inside the temple were a huge fire pit and a conduit system. Archeologists speculate that the water comes from the temple’s terrace to collect itself on the pit. • Discoveries Inside the temple were some very interesting things found by archeologists. They have discovered lion and leopard bones that were speculated for the offerings to the gods. Also they have discovered ritual objects and bones that were buried. Religious Beliefs • Ziggurat’s building period took more extensive time than Egypt’s pyramids. From the third millennium to 600 BC, Mesopotamia’s tradition remained longer because they represent their Gods and were a symbolic trademark for the Mesopotamian civilizations. • Mesopotamia’s temples were very valuable for its nations because it serves as an interaction between their people and their worshipped deities. Ziggurats were very important to its ancestors, as these structures connected communities together. These nations believed that their gods rested high up in the sky and they believed that this monumental temple of theirs connected Heaven and Earth to communicate with them. Their temples represent their God’s power. • They assumed that the higher the ziggurat was, the closer they were to their gods and that rested in...

Printing

...the cylinder is enveloped with the printing plate with the help of double sided tape, it allows nonstop printing without resetting the machine after every print cycle. Flexography is a simple method. It starts with collecting maximum liter of ink in the container which is in constant access to the printer. The ink is constantly fed to the machine in bulk to keep the printing process constant and steady. Later ‘anilox’ rolls to collects ink on the press. Anilox is cylindrical in shape which contains numerous microscopic recesses designed for retaining ink. These shapes include: * pyramid recesses * truncated pyramid recesses or * hexagonal shaped cells . The advantage of using an anilox is of metering the amount of ink transferred to printing plate. Also, helps retaining large amount of ink which will result in increasing the in transfer amount and thickness of printed width. Various methods use different shapes of cell and recess volume, which is to print single color on a large area, an anilox...

Math Essay

...The history of Geometry started in Ancient Egypt around 3000 B.C.E. Egyptians used an early stage of geometry when surveying the land, construction of pyramids, and astronomy. And around 2900 B.C.E. they began using their knowledge to construct pyramids with four triangular faces and a square base. It was created because it was a collection of empirically discovered principles concerning lengths, angles, areas, and volumes, which were developed to meet some practical need in surveying, construction, astronomy, and various crafts. It was used in Babylonia and in the Indus Valley by the Egyptians, Babylonians, and the people of the Indus Valley but the creators were Pythagoras, Euclid, Archimedes, and Thales. Pythagoras was the first pure mathematician although we know little about his mathematical achievements. He was also, a greek philosopher and created a movement called Pythagoreanism. Euclid is sometimes called Euclid of Alexandria. He is also called the “Father of Geometry” and his elements were one of the most influential works in the history of mathematics, which served as a textbook used for teaching mathematics (especially Geometry) from when it was published till the late 19th century to early 20th century. In the Elements he included the principles of what is now called Euclidean Geometry. Euclidean Geometry is a mathematical system and consists of in a small set of appealing postulates that are accepted as true. In fact, Euclid was able to come up with a great...

Geometry

...Geometry Geometry is all about shapes and their properties. If you like playing with objects, or like drawing, then geometry is for you! Geometry can be divided into: Plane Geometry is about flat shapes like lines, circles and triangles ... shapes that can be drawn on a piece of paper Solid Geometry is about three dimensional objects like cubes, prisms and pyramids. Plane Geometry Plane geometry is all about shapes like lines, circles and triangles ... shapes that can be drawn on a flat surface called a Plane (it is like on an endless piece of paper). Plane A plane is a flat surface with no thickness. Our world has three dimensions, but there are only two dimensions on a plane. Examples: • • length and height, or x and y And it goes on forever. Examples It is actually hard to give a real example! When we draw something on a flat piece of paper we are drawing on a plane ... ... except that the paper itself is not a plane, because it has thickness! And it should extend forever, too. So the very top of a perfect piece of paper that goes on forever is the right idea! Also, the top of a table, the floor and a whiteboard are all like a plane. Imagine Imagine you lived in a two-dimensional world. You could travel around, visit friends, but nothing in your world would have height. You could measure distances and angles. You could travel fast or slow. You could go forward, backwards or sideways. You could move in straight lines, circles, or anything so long...

Mayans Disappearance

...There is no definite reason for why they declined so rapidly, from the late eighth through the end of the ninth century, something unknown happened, normal cities in the southern lowlands were abandoned, and by A.D. 900, Mayan civilization in that area had collapsed. The reason for this mysterious decline is unknown, though scholars have developed several different and similar theories (History.com). Many people have participated in the quest to find the reason for their mysterious vanish act, a variety of explanations have come to the surface. Some of these could have included “overpopulation and overuse of the land, endemic warfare and drought” all of these could have been the reason for their dissaperance (History.com). Some scholars believe the only reason from their disappearance is because of a dramatic climate change that resulted in a massive drought that hit the Mayan cities. To test their hypothesis Arizona State University analyzed archaeological information from across the Yucatan to reach a better understanding of the environmental conditions when the area was abandoned. During their research they found, severe rain reductions in this area, and a rapid rate of deforestation. Deforestation is when a forest or wooded area is reduced in size rapidly. We know the Mayans did this by burning and chopping down more and more forest to clear land for agriculture. Another way Mayans set themselves to certain...

...1)What does the study of humanities involve? What is the relevance of humanities in architecture? 1.The study of humanities involves academic disciplines that study human culture and history. The humanities include ancient and modern languages ,literature, philosophy, religion, and visual and performing arts such as music and theatre. We learn about distant cultures or past cultures. Through the exploration of humanities we learn how to think creatively and critically to reason and ask questions. These efforts preserve the great accomplishments of the past help us understand the world we live in and give us tools to imagine the future. 2.What are the broad divisions of human history? Write a brief on each. Prehistory (meaning "before history", or "before knowledge acquired by investigation", from the Latin word for "before," præ, and historia) is the span of time before recorded history or the invention of writing systems. Prehistory refers to the period of human existence before the availability of those written records with which recorded history begins. More broadly, it can refer to all the time preceding human existence and the invention. The term "prehistory" can refer to the vast span of time since the beginning of the Universe, but more often it refers to the period since life appeared on Earth, or even more specifically to the time since human-like beings appeared.[4][5] In dividing up human prehistory, prehistorians typically use the three-age system, whereas scholars...
