Question

\a man has 40 ft. Of fencing to put around a rectangular garden. If the length is 4 times the width, find the dimensions of his garden.

Answer 1

Length (L): 4w

width (w): w

Perimeter (P) = 2L + 2w

40 = 2(4w) + 2(w)

40 = 8w + 2w

40 = 10w

4 = w

Length (L): 4w = 4(4) = 16

Answer: width = 4 ft, length = 16 ft
