Problem definition: Calculate the usable area in square feet of house. Assume that the house has a maximum of four rooms, and that each room is rectangular. A. Problem Analysis – Following the directions in the assignment, clearly write up your problem analysis in this section.
Description:
The program first accepts the number of rooms. Then for each room the dimensions are taking (Length and Width). With all the dimensions recorded for each room, Area is calculated as Length by Width, using the formula for area calculation of a rectangle (Length*Width). The final unused area is the sum of all the areas from the number of room specified.
Analysis:
The number of rooms will be held in a variable N, Length and Width for each room will be held in LN and WN respectively. With N representing the room number. AreaTotal and AreaTemp are used to hold the final area values and the temporal values of area for each room respectively. To keep track of which room’s dimension or area is being dealt with, the variable Count will be used.
Variables to use: 1. N : Number of Rooms 2. Count : Count for loop 3. AreaTemp: Temporal area 4. AreaTotal : Total area 5. LN : Length of Room number N 6. WN: Width of Room number N B. Program Design – Following the directions in the assignment, clearly write up your problem design in this section and comment your pseudocode.
Pseudo Code: 1. Enter the number of rooms : N 2. Set Count = 0 3. If Count < N a. For Count < Number of Rooms // if count is less than the number of rooms i. Enter Dimension for Room number : Count +1 // ii. Lcount +1 , Wcount+1 iii. Count = Count + 1 // Increment count by 1. 4. Area Calculation 5. Set Count = 0 6. Set AreaTemp = 0 7. Set AreaTotal = 0 8. If Count < N b. For Count < Number of Rooms // if count is less than the number of rooms iv. AreaTemp = Lcount +1 x Wcount+1 v. AreaTotal = AreaTotal + AreaTemp vi. Count = Count + 1 // Increment count by 1. 9. Total Unused Area = AreaTotal

C. Program Comments and Test Data – Following the directions in the assignment, include your test data and expected results in this section.

Test Cases: 1. Room Number = 2 , a. Room 1 : Length1 = 20, Width1 = 20 , b. Room 2 : Length1 = 22, Width1 = 10 c. Output = (20*20) +(22*10) = 620 2. Room Number = 1 d. Room 1: Length1 = 10, Width1 = 40 e. Output = (10*40) = 400 3. Room Number = 3 f. Room 1 : Length1 = 9, Width1 = 2 g. Room 2 : Length2 = 5, Width2 = 6 h. Room 3 : Length3 = 2, Width3 = 18
Output: (9*2)+(5*6)+(2*18) = 84
