Let $A = (0,0)$ and $B = (b,3)$ be points on the coordinate plane. Let $ABCDEF$ be a convex equilateral hexagon such that $\angle FAB = 120^\circ,$ $\overline{AB}\parallel \overline{DE},$ $\overline{BC}\parallel \overline{EF,}$ $\overline{CD}\parallel \overline{FA},$ and the y-coordinates of its vertices are distinct elements of the set $\{0,3,6,9,12,15\}.$ The area of the hexagon can be written in the form $p\sqrt {q},$ where $p$ and $q$ are positive integers and q is not divisible by the square of any prime. Find $p + q.$
