If the hypotenuse of a right triangle is 13 and one of its legs is 5, find the area fo the triangle.
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.

Use 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.

Use 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.
