He hypotenuse of a right triangle is three times the length of one of the legs. the length of the other leg is 648‾‾‾‾√648 feet.
pantera1 [17]
Let length of  the hypotenuse = 3x and length of given leg be x feet.

then (3x)^2 = x^2 + 648
8x^2 = 648
x^2 = 81


so x = 9 and 3x = 27

Hypotenuse is 27 feet and the leg equals 9 feet.
