Question

Which system of equations below can be used to solve the following problem?

The of a rectangular room is 80 square feet. If the length of one side of the room is 8 feet what is the perimeter of the room?

Answer 1

C.

Explanation:

1. Find the area part of the equation.

Area is base×height, so if we substitute 8 as the base and w as the height, A=8w

2. Find the perimeter of the equation.

Perimeter of a rectangle is 2(base + height), so in this case, it will be

P=2(8 + w), or C.
