If you are a novice in this kind of problems, you can solve it using the Pythagorean theorem


 = ,


x^2 + x^2 + 10x + 25 = 625,

2x^2 + 10x = 600,

2x^2 + 10x = 600,

x^2 + 5x - 300 = 0,

(x+20)*(x-15) = 0  ====>  x = 15  is your shorter leg  and x = 15+5 = 20  is your longer leg.


Then your perimeter is  15 + 20 + 25 = 60 feet.



Or, if you are not a novice and just know about a right angled (3-4-5)-triangle, then you will get the answer instantly without any equations.
