Question

A new city park is a rectangular shape. the length is triple the width. it will take 240 meters of fencing to go around the park. find the length and width of the park.

Answer 1

Length (L): 3w

width (w): w

Perimeter (P) = 2L + 2w

240 = 2(3w) + 2(w)

240 = 6w + 2w

240 = 8w

30 = w

Length (L): 3w = 3(30) = 90

Answer: width = 30 meters, length = 90 meters
