Try this. I just googled
ABCD is aparallelogram in which BCis produced to E such thatCE = BC
and got this hit, among others:

It is the same problem, just approached from a different side (as it were).
In the figure, ABCD is aparallelogram in which BCis produced to E such thatCE = BC. AE intersects CDat F. Show that ar (∆BDF)= 14ar (ABCD).
