The Perimeter of a certain isosceles right triangle is

The Perimeter of a certain isosceles right triangle is 16+16√2. What is the length of the hypotenuse of the triangle? A) 8 B) 16 C) 4√2 D) 8√2 E) 16√2

For such problems, Imagine a Iso Rt angle T with sides x√2, x√2 and hyp as x (Not the conventional sides as x, x, x√2).....
hence... x + x√2 = 16 + 16√2 ...The ans as B.
