L = Length
W = Width
P = Perimeter
L = W + 6
P = 2 L + 2 W = 2 ( L + W )
120 = 2 ( W + 6 + W )
120 = 2 ( 2 W + 6 )
120 = 4 w + 12 Subract 12 to both sides
120 - 12 = 4 W
108 = 4 W Divide both sides by 4
27 = W
W = 27 in
L = W + 6
L = 27 + 6
L = 33 in
W = Width
P = Perimeter
L = W + 6
P = 2 L + 2 W = 2 ( L + W )
120 = 2 ( W + 6 + W )
120 = 2 ( 2 W + 6 )
120 = 4 w + 12 Subract 12 to both sides
120 - 12 = 4 W
108 = 4 W Divide both sides by 4
27 = W
W = 27 in
L = W + 6
L = 27 + 6
L = 33 in
