Let ABCDEFA B C D E F be a convex hexagon with the following properties. (a) AC¯\overline{A C} and AE¯\overline{A E} trisect ∠BAF\angle B A F. (b) BE¯‖CD¯\overline{B E} \| \overline{C D} and CF¯‖DE¯\overline{C F} \| \overline{D E}. (c) AB=2AC=4AE=8AFA B=2 A C=4 A E=8 A F. Suppose that quadrilaterals ACDEA C D E and ADEFA D E F have area 2014 and 1400, respectively. Find the area of quadrilateral ABCDA B C D.

Original LaTeX notation
Let $A B C D E F$ be a convex hexagon with the following properties. (a) $\overline{A C}$ and $\overline{A E}$ trisect $\angle B A F$. (b) $\overline{B E} \| \overline{C D}$ and $\overline{C F} \| \overline{D E}$. (c) $A B=2 A C=4 A E=8 A F$. Suppose that quadrilaterals $A C D E$ and $A D E F$ have area 2014 and 1400, respectively. Find the area of quadrilateral $A B C D$.
