Hey guys! I came upon this problem studying for the GRE and I spent 20 minutes on it without success. I'm sure there's a long messy way to answer the question, but there should also be a simple easier way as well. Please help!

An isosceles right triangle has an area of 2x^2 + 2x + 1/2. What is the triangles perimeter?

A) 3(x+1)

B) [sqrt]2(X^2 +1)

C) (2x-1)(2x+1)

D) (2x + [sqrt]2)(2x+1)

E) 2x + [sqrt]2

Thanks folks!
