^I forgot how to do that. But do you know the pythagoream theorm? That can help you answer the problem.

goldphenoix · Answer

The pythagoream theorm looks like: $$\large \large a^2 + b^2 = c^2$$ A and B represent the legs, while C represent the hypotenuse. So what do you think you have to do?

anonymous · Answer

It doesn't give me the leg only the hypotenuse.

Oh really? |dw:1372027294407:dw| Do you see it now?

goldphenoix · Answer

I have to go soon, but you see the triangle, right?
The 2 leg (a,b) is 16.
So the equation would look like: $$\large \large 16^2 + 16^2 = c^2$$ Solve your equation, and c would be the diagonial of the square. :)

Yes, I see it. Thanks.
