.
Let x = the length of the hypotenuse, in feet.

Then the legs are (x-2) ft and (x-4) ft,

and you have a quadratic equation

x-2%29%5E2 + %28x-4%29%5E2 = x%5E2.

Simplify, and you will get

x%5E2+-+12x+%2B+20 = 0.

There are two roots, 10 and 2.

The smaller doesn't fit. The greater does work.

Answer. 10 ft.
