You can put this solution on YOUR website!
h for height, b for base;
h=b-14.

%281%2F2%29b%2Ah=520
%281%2F2%29b%28b-14%29=520
b%5E2-14b=1040
b%5E2-14b-1040=0
Note that discriminant is 66%5E2
-
b=%2814%2Bsqrt%2866%5E2%29%29%2F2
and you can continue and finish this.

The quadratic equation in b is factorable but general solution is more comfortable here.
