Length (L): 2w - 3

width (w): w

Perimeter (P) = 2L + 2w

                18 = 2(2w -3) + 2(w)

                18 = 4w - 6 + 2w

                18 = 6w - 6

                24 = 6w

                  4 = w

Length (L): 2w - 3   = 2(4) - 3   = 8 - 3   = 5

Answer: width = 4 meters, length = 5 meters
