Question

The two leg lengths of a triangle are 21 and 28 ft. What is the length of the hypotenuse?

Answer 1

Answer

The length of the hypotenuse is 35 feet.

Explanation

This is the formula to find the hypotenuse.

$l^{2} + l^{2} = h^{2}$

One leg is 21 feet. The other is 28 feet. Now insert those into the formula.

$21^{2} + 28^{2} = h^{2}$

$h^{2}=1225$

Now to find what h is you should find the square root of 1225.

$\sqrt{1225} =35$

So the length of the hypotenuse is 35 feet.
