. Susan's room is 9 feet long. The area of the room is 54 square feet.What is the perimeter of her room?

A = Area
W = Width
L = Length
P = Perimeter
A = W * L
54 = W * 9 Divide both sides by 9
54 / 9 = W
6 = W
W = 6 ft
P = 2 ( W + L )
P = 2 ( 9 + 6 )
P = 2 * 15
P = 30 ft

A = L * W
54 = 9 * W
54/9 = W
6 = W
P = 2L + 2W
P = (2 * 9) + (2 * 6)
P = 18 + 12
P = 30 feet
