    ABCD is a convex quadrilateral.
    AE=ED
    DF=FC
    Symmetrics of B with respect to E and F are K and L
    All the areas of the triangles in the figure are successor numbers.
    Find area of triangular region DKL.

    Unfortunately, there are no "F", "K", or "L" in your picture. Also, as you were told in the first response, "please show some attempt/work so we may help you from there".

    I have long suspected that there is somethings very fishy about kastamonu.
    I will bet that he/she is a tutor who is working with students preparing for exams. She/he comes to a difficult question not readily workable. So it is post here. One of us show-offs will hand over a solution free of charge. Just review the posts of kastamonu. That review will show mine is a reasonable guess about what kastamonu is all about.
    @ kastamonu, can you please show me wrong. Post some work.
    Thanks from DenisB

    I am not a tutor. But if you bet and put Money in it and send them to me, I will gladly show you my certified accountant card.
    I have no students. I am doing this for my self. 3 weeks later I will not be here. I will have an exam and after that I will go under a brain surgery operation. I postponed it because of the exam and it is very risky. But you are right for one thing "She/he comes to a difficult question not readily workable. So it is post here. One of us show-offs will hand over a solution free of charge."

    I solved the problem. Not as hard as I had thought. Wittenbauer helps a lot.
