The length of a rectangle is 4 cm longer than the width. if the perimeter of the rectangle is
20 centimeters, what is the area of the rectangle?

area = 21

Step-by-step explanation:

20 - 4(2) = 20 - 8 = 12

12/4 = 3

2(3 + 4) + 2(3) = 2(7) + 2(3) = 14 + 6 = 20

length (l) = 7

width (w) = 3

area = lw = (7)(3) = 21

area = 21

i wasnt sure how to explain it but i hope this makes sense
