Question

One side of a rectangle is 3 inches shorter than the other side, and the perimeter is 54inches. What are the dimensions of the rectangle? Which of the following could be used to solve the problem?

Answer 1

15 and 12

Explanation:

Set the two sides as x and y

y=x-3

P = 2w+2l

2x+2(x-3) = 54

4x-6=54

4x=60

x=15

y=12
