The perimeter of a rectangle is 48m. If the width were doubled and the length were
increased by 24m, the perimeter will be 112m. What are the length and width of the rectangle?

Answer:

Step-by-step explanation:

2W + 2L = 48

   W + L = 24

         L = 24 - W

    2(2W) + 2(L + 24) = 112

          4W + 2L + 48 = 112

4W + 2(24 - W) + 48 = 112

 4W + 48 - 2W + 48 = 112

                           2W = 16

                              W = 8

      L = 24 - 8

      L = 16
