leonid [27]

Length (L): w + 3.5

width (w): w

Perimeter (P) = 2L + 2w

                31 = 2(w + 3.5) + 2(w)

                31 = 2w + 7 + 2w

                31 = 4w + 7

               24 = 4w

                 6 = w

Length (L): w + 3.5   = (6) + 3.5   = 9.5

Answer: width = 6 inches, length = 9.5 inches
