Program Analysis

In this program the overall goal is to obtain the overall square feet in a four bedroom house. In order to calculate the correct output we will need the correct input. I will obtain the required output from the given input by multiplying length x width to find the number of square feet in each room and then add the amount of the four rooms together.

• Room1 = Room1Length * Room1Width

• Room2 = Room2Length * Room2Width

• Room3 = Room3Length * Room3Width

• Room4 = Room4Length * Room4Width

• TotalSquareFeet = Room1 + Room2 + Room3 + Room4

Input data: Input the variable Room1Length, Room1Width, Room2Length, Room2Width, Room3Length, Room3Width, Room4Length and Room4Width

Calculations: TotalSquareFeet = Room1 + Room2 + Room3 + Room4

Perform Calculations Module

Declare TotalSquareFeet As Float

Set Room1 = Room1Length *Room1 Width

Set Room2 = Room2Length *Room2Width

Set Room3 = Room3Length *Room3 Width

Set Room4 = Room4Length *Room4Width

//Calculate total square feet

Set TotalSquareFeet = Room1 + Room2 + Room3 + Room4

//Output the result

Output results module

Write “The total square footage of the house is:” TotalSquareFeet
