Question

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

Answer 1

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.

`√(1225) =35`

So the length of the hypotenuse is 35 feet.

Answer 2
