Problem Statement

In triangle ABC ABC the medians AD \overline{AD} and CE \overline{CE} have lengths 18 and 27, respectively, and AB \equal{} 24. Extend CE \overline{CE} to intersect the circumcircle of ABC ABC at F F. The area of triangle AFB AFB is mn m\sqrt {n}, where m m and n n are positive integers and n n is not divisible by the square of any prime. Find m \plus{} n.
