These are some neat questions. Where did you get them from?

Triangles $\displaystyle ABC$ and $\displaystyle CBE$ are similar.
From that, you get $\displaystyle BC$.
From acute triangle $\displaystyle EBF$ you can get $\displaystyle FE=CF=a$, and from that wanted area $\displaystyle a^{2}$.

I assume you meant "right triangle $EBF$".
