(a)Use the area formula of a rectangle to find its length.

Find the length of the rectangle shown. Area 20 cm².

A = L x W

Replace A with 20 and W with 4

20 = 4 L

divide both sides by 4

So, the length L is 5 inches.

(b)Use the perimeter formula for a rectangle to find its length.

Find the length of the rectangle shown. P = 2(L+W)

Replace P with 18 and W with 4

18 = 2(L+4)

divide both sides by 2

9 = (L+4)

So, the length L is 5 inches.
