The length of a rectangle is 4 cm longer than its width. If the perimeter of the rectangle is 40 cm, find its area

96

Step-by-step explanation:

The length of a rectangle is 4 cm longer than its width. If the perimeter of the rectangle is 40 cm, find its area

width + 4 = length

width = width

2l + 2w = p

width+width +width +width +4 +4 = 40

4width +8  = 40

4width =  32

width = 8

length x width = area

width = 8

length = 12 (width + 4)

12x 8 =  96
