twice length + twice width = perimeter
In this example, L= 3W
2(3W)+2(W)=64
8W=64
W=6
L =3W
L=18

the answer to number 20 is B...12
The rectangle is 9 inches wide X 27 inches long. Clue: width is X; length is 3 times width (3X). Perimeter is width plus length times two (X + 3X times 2 = 8X). 8X = 72; X = 9. 3X = 27. Proof: 9 + 9 (2sides) +27 + 27 (2 lengths) = 72.
