The perimeter of a rectangle is 56 meters. The width of the rectangle is 4 meters less than the length.Find the length and the width.

 

Answer:

16 (length)

12 (width)

Step-by-step explanation:

The perimeter of a rectangle is 56 meters. The width of the rectangle is 4 meters less than the length.Find the length and the width.

Given: perimeter = 56

           let W = width

                 L = length

perimeter = 56 = 2L + 2L

             W = L - 4

             56 = 2L + 2(L - 4)

             56 = 2L + 2L - 8

             64 = 4L

             L = 16 (length)

             W = 16 - 4 = 12 (width)
