Question

A rectangular field is three times as long as it is wide. If the perimeter of the field is 600 feet, what are the dimensions of the field?

Answer 1

Length (L): 3w

width (w): w

Perimeter (P) = 2L + 2w

600 = 2(3w) + 2(w)

600 = 6w + 2w

600 = 8w

`(600)/(8) = (8w)/(8)`

75 = w

Length (L): 3w = 3(75) = 225

Answer: Length=225 feet, width=75 feet
