Question

The dimensions (width and length) of room1 have been read into two variables : width1 and length1. The dimensions of room2 have been read into two other variables : width2 and length2. Write a single expression whose value is the total area of the two rooms.

Answer 1

width1*length1+width2*length2 = totalArea

Explanation:

To calculate the area of a rectangle you should multiply it's base by it's high.

In this case width times length for a given room

width1 * lenght1 = area of room1

width2 * lenght2 = area of room2

totalArea = area of room1+area of room2

This asumes that there is no overlaping between the rooms and that the rooms are rectangular
