Ratio of areas in parallelogram with intersecting diagonals

[dekoi]

Im back with yet another geometry problem.

In the parallelogram ABCD, AE:ED = 1:2. B is joined to E on AD. A is joined to opposite vertex C. Intersecting point labelled F.
Determine the ratio of the area of ABF to quadrilateral EFCD.

I have tried a variety of methods, yet can't seem to get the right answer (3:11). Please help me any way you can.
