Question

The length of a rectangle is equal to three times it’s width. If the perimeter is equal to 72 feet, what is the length of the rectangle?

Answer 1

27 feet

Explanation:

Let x represent the width

Let 3(x) represent the length

Perimeter = L + L + W + W

72 = 3x +3x + x + x

72 = 8x

`(72)/(8) = (8x)/(8)`

9 = x

∴ Length = 3(9) = 27 feet
