If the length and width of rectangle A are 10 percent less and 30 percent less,
respectively, than the length and width of rectangle B, the area of A is equal
to what percent of the area of B?
:
Let L = length of rectangle B
Let W = width of B
then
.9L = Length of rectangle A
.7W = width of A
:
%28.9L%2A.7W%29%2F%28L%2AW%29 = %28.63LW%29%2F%28LW%29
Cancel LW
.63%2F1 * 100 = 63%
