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?
B) [sqrt]2(X^2 +1)
D) (2x + [sqrt]2)(2x+1)
E) 2x + [sqrt]2
