magoosh is really helpful for me in preparing the new gre,especially in verbal section.feels lucky to found it..:)thanks magoosh.

I’m glad you find the posts helpful, I’ll pass along the thanks to the other authors! 🙂

Area of square ABCD = 25 so side = 5

Side of small shaded square = x

Side of large shaded square = 5-x

(5-x)^2 / x^2 = 9

5-x/x = 3

5-x = 3x

4x=5

x=5/4

The answer is B) 5/4
