Step-by-step explanation:    TS 5 15 8 26

L = W + 4

Area = 45 ft²

Area = LW

Area = (W +4)(W) = 45 ft²

         W² + 4W - 45 = 0        solve for W

         (W + 9)(W - 5) = 0

         W = -9 or 5                a minus 9 width makes no sense

     L = W + 4

     L = 5 + 4

W = 5 ft   L = 9 ft
