Question

The length of a rectangular garden is three times the width if the perimeter is 32 meters, what are the dimentions of the garden

Answer 1

Length (L): 3w

width (w): w

Perimeter (P) = 2L + 2w

                32 = 2(3w) + 2(w)

                32 = 6w + 2w

                32 = 8w

                  4 = w

Length (L): 3w   = 3(4)   = 12

Answer: width = 4 meters, length = 12 meters
