In the diagram, ABCD is a square. Point E is the midpoint of AD. Points F and G lie on CE, and H and J lie on AB and BC, respectively, so that FGHJ is a square. Points K and L lie on GH, and M and N lie on AD and AB, respectively, so that KLMN is a square. The area of KLMN is 99. Find the area of FGHJ.
