Question

Dev has a rectangular garden in his backyard. The length is 2 feet greater than twice the width.

A. Write an equation to determine the perimeter of the garden.

B. What is the perimeter of Dev’s garden if the width is 5 feet?

Answer 1

Explanation:

L = 2W + 2 (length is 2 ft greater than twice the width)

A. The perimeter of the garden is P = 2L + 2W, which here is:

P = 2(2W + 2) + 2W, or P = 4W + 4 + 2W, or P = 6W + 4

B. If W = 5 ft, then P = 6(5 ft) + 4 ft = 34 ft
