so because the triangle is isosceles.
when
is called by
.
We know that
since E and D are tangent points to a circle.
They have
since D and F are tangent points only to circle.
Thus, if the perimeter is 32, the following is the result:

Therefore the length of 
C^2-a^2=b^2 b^2=81-36=45 x^2/36-y^2/45=1?
252 is the answer hope it helps
