**MathMate**, Sunday, September 11, 2011 at 3:44pmUse Pythagoras theorem:

hypotenuse² = side1²+side2²l

=(√11)²+(√11)²

= 11 + 11

= 22

Therefore

hypotenuse = √22

**MathMate**, Sunday, September 11, 2011 at 7:14pmThe method I have shown above is more general, and applies to any right-triangle.

For a 45-45-90 triangle, you were close with the answer. A short-cut would be to multiply each side by √2, which makes:

√2 * √11

=√22.
