Rectangle A has sides a and b, and rectangle B has sides c and d. If a/c=b/d=3/4, what is the ratio of rectangle A’s area to rectangle B’s area? Select:
A) 3/4 B) 9/16 C) 16/3 D) 4/3 E) 3/16
The area of rectangle A is ab.   c=4a/3 and d=4b/3.   The area of rectangle B is cd=16ab/9.   The ratio of rectangle A's area to rectangle B's area is ab / (16ab/9) = 9/16.   The answer is 9/16.
