Question

9. The Perimeter of a rectangle is numerically equal to its area. If the width of a rectangle is 2cm, then the length is ​

Answer 1

Given perimeter of rectangle = Area of rectangle and width = 11/4

          2(L+W) = L*W

          2(L + 11/4) = 11L/4

          2L + 11/2 = 11L/4

          11L/4 - 2L = 11/2

          3L/4 = 11/2

           6L = 44

            L = 44/6

            L = 22/3.
