# The ratio between the perimeter and the width of a rectangle is 5 : 1.

The ratio between the perimeter and the width of a rectangle is 5 : 1. If the area of the rectangle is 150 sq. cm, what is the length of the rectangle?

## Answer/Solution

15 cm

### Steps/Work

2L+2W = 5W

L = 3W/2

W*L = 150

3W^2/2 = 150

W^2 = 100

W = 10

L = 3(10)/2 = 15

The answer is B.

L = 3W/2

W*L = 150

3W^2/2 = 150

W^2 = 100

W = 10

L = 3(10)/2 = 15

The answer is B.
