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.
