Program description: I calculated the usable area in square feet of a house. Assume that the house has a maximum of four rooms, and that each room is rectangular. I wrote pseudo code statements to declare 4 Integers and labeled them homesqft, room1, room2, room3, and room4. Each room will have its length and width to calculate its area.
Analysis:
Test Case #
Input
Expected Output

1
Room1: length=10, width=14
Room2: length=9, width=10
Room3: length=12, width=12

542 sqft

2
Room1: length=10, width=10
Room2: length=11, width=12
Room3: length=11, width=12
Room4: length=13, width=14

546 sqft

3
Room1: length=8, width=10
Room2: length=10, width=12
Room3: length=11, width=14
Room4: length=12, width=14
542 sqft

Main module Declare homesqft As Float Declare room1_length, room1_width, room2_length, room2_width, room3_length, room3_width, room4_length, room4_width As Float Call Input Data module Call Perform Calculations module Call Output Results module

End Module
Input Data module Write "Please enter Room 1 Length: " + room1_length Write "Please enter Room 1 Width: " + room1_width Write "Please enter Room 2 length: " + room2_length Write "Please enter Room 2 width: " + room2_width Write "Please enter Room 3 length: " + room3_length Write "Please enter Room 3 width: " + room3_width Write "Please enter Room 4 length: " + room4_length Write "Please enter Room 4 width: " + room4_width

Perform Calculations module Set room1_sqft = room1_length * Room1_width Set room2_sqft = room2_length * Room2_width Set room3_sqft = room3_length * room3_width Set room4_sqft = room4_length * room4_width Set homesqft = room1_sqft + room2_sqft + room3_sqft + room4_sqft Output Results module Write "The item is: " + homesqft
