Question

The length of a rectangular garden is 8 feet longer than its width. the garden's perimeter is 184 feet. find the length of the garden.

Answer 1

Width: W
Length: L = W + 8

Perimeter = 2W + 2L = 2(W) + 2(W+8) = 184 (ft)

Solving for W: 2W + 2W + 16 = 184 (ft)
4W = 168 ft, and so W = 42 ft.

The length, L, is (42 + 8) ft = 50 ft. (answer)
