Question

A rectangle has a perimeter of 36 centimeters. The length of the rectangle is five centimeters more than the width. What is the length of the rectangle?

Answer 1

11.5 cm

Explanation:

Set up a system of equations and simplify.

l = w + 5

2l + 2w = 36

Substitute w + 5 for l

2w + 10 + 2w = 36

4w + 10 = 36

4w = 26

w = 6.5

l = 6.5 + 5

l = 11.5
