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

Answer:

27 feet

Step-by-step explanation:

Let x represent the width

Let 3(x) represent the length

Perimeter = L + L + W + W

72 = 3x +3x + x + x

72 = 8x

$\frac{72}{8} = \frac{8x}{8}$

9 = x

∴ Length = 3(9) = 27 feet
