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?

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

step-by-step explanation:

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
