Use the Pythagorean Theorem to find 'h'.

For right triangles, where 'a' and 'b' are the two legs and 'c' is the hypotenuse.
Divide the base by 2 to find the base length of one of the right triangles. 32/2 = 16. Now apply the Pythagorean Theorem:

Simplify:

Subtract 256 to both sides:

Take the square root of both sides:

So the height is 12cm. Apply the formula for the area of a triangle:
