# Interesting Parallelogram

Geometry Level 4

A point $$X$$ is drawn on the diagonal of a parallelogram $$ABCD$$. The lines parallel to the sides through $$X$$ are constructed, Quadrilaterals $$P$$ and $$Q$$ are formed as shown on the diagram.

Given that $$Q$$ has base $$12$$, perpendicular height $$4$$ and that the area of $$ABCD$$ is $$200$$, find the sum of all possible values of the base of $$P$$.
