I know a hypotenuse the side of a right triangle opposite the right angle. You can't multiply the hypotenuse with one of the legs.

**Marth**, Thursday, August 20, 2009 at 11:33amUse Pythagorean Theorem to find the other side. a^2 + b^2 = c^2

You have a = 5, and c (the hypotenuse) = 13, so

5^2 + b^2 = 13^2

b = ? (it's a whole number)

The area of a triangle is (1/2) * base * height

After you have found b, you have the two sides a and b - find the area.

**PsyDAG**, Thursday, August 20, 2009 at 11:39amUse the Pythagorean Theorem to find the length of the other leg. Then use that to find the area.

I hope this helps. Thanks for asking.
