Right Triangle one leg is 400ft. long. The hypotenuse of the triangle is 200ft. longer than the other leg. What is the dimensions of this triangle?

let the other leg be x , where x is in hundred of feet (I am avoiding large numbers)
x^2 + 4^2 = (x+2)^2
x^2 + 16 = x^2 + 4x + 4
4x = 12
x=3 > 300 ft
So the sides are 200, 300 and 500
