Hi, I am sure by 'The rectangle A has a by b ', you mean rectangle has sides a and b.. the ratio of legth and breadth of both the rectangles is 3/2.. so the area will be in the ratio $$\frac{3^2}{2^2}=\frac{9}{4}$$ D _________________ CEO Status: GMATINSIGHT Tutor Joined: 08 Jul 2010 Posts: 2977 Location: India GMAT: INSIGHT Schools: Darden '21 WE: Education (Education) Re: The rectangle A has a by b and another rectangle B has c by d.

"The rectangle A has a by b and another rectangle B has c by d" I find it NON-GMAT LANGUAGE a/c=b/d=3/2 i.e. a/b = c/d i.e. the two rectangles are similar rectangles Ratio of Areas = Square of ratio of their corresponding sides i.e. Ratio of Areas of Rectangle A and B = (a/c)^2 = (3/2)^2 = 9/4 ANswer: Option D _________________ Prosper!!!

The rectangle A has a(width) and b(height) and another rectangle B has c(width) and d(height). If a/c=b/d=3/2, what is the ratio of the rectangle A’s area to the rectangle B’s?

A. 3/2
B. 3/4
C. 9/2
D. 9/4
E. 27/8

-> a=3k, c=2, and b=3m, d=2m
Then, the ratio of the area is (3k)(3m):(2k)(2m)=9km:4km=9:4=9/4

We can let a = b = 12.

We can let c = d = 8.

The area of rectangle A is 12 x 12 = 144.

The area of rectangle B is 8 x 8 = 64.

The ratio of the area of rectangle A to that of rectangle B is:

144/64 = 18/8 = 9/4
