GMAT prep math problem

[mahermir]

hi everyone..
Suddenly I am blocked here-

Perimeter of Isosceles triangle is 16+16rt2.what is the length of the hypotenuse?

Can anyone solve the math for me?

[ps63739]

I guess that right angle triangle, in that case
Assume hypotenuse = x
Sides be x/sqrt2, and x/sqrt2

Add all you get Perimeter = x + x sqrt2 = Comapre with what's given.. x = 16.
