The ratio of similarity between BED and BAC is 11:15; the ratio of their areas is 11^2:15^2 = 121:225.

The ratio of similarity between EAF and BAC is 4:15; the ratio of their areas is 4^2:15^2 = 16:225.

The area of BED is 121/225 of the area of BAC; the area of EAF is 16/225 of the area of BAC; what is left is the area of the parallelogram.
