Question 11
Let $ABCD$ be a parallelogram with $\angle BAD \lt 90^\circ.$ A circle tangent to sides $\overline{DA},$ $\overline{AB},$ and $\overline{BC}$ intersects diagonal $\overline{AC}$ at points $P$ and $Q$ with $AP \lt AQ,$ as shown. Suppose that $AP = 3,$ $PQ = 9,$ and $QC = 16.$ Then the area of $ABCD$ can be expressed in the form $m\sqrt{n},$ where $m$ and $n$ are positive integers, and $n$ is not divisible by the square of any prime. Find $m + n.$
