(1) There is a 25% difference between the red and blue cloths in one of the dimensions.

Call each side of the red square x. Technically we are looking for x^2 but since this is data sufficiency all we need is x.

Therefore the sides of the blue cloth are (x+2) & (x-1) respectively.

1) This gives us two possible scenarios.

Either:

x+2 = 1.25x

or

x = 1.25(x-1)

x has two possible values --> 8 or 5. Therefore insufficient.

2) This was one of our options from statement 1 but now we know we don't have any possibility other than the x + 2 = 1.25x. Therefore x = 8
SUFFICIENT

Final Answer: B
