In the above diagram, $$\square ABCD$$ is a square with side $$\overline{AD}$$ extended to point $$E$$, and $$\overline{BE}$$ is a straight line. If the length of $$\overline{BC}$$ is $$\lvert \overline{BC}\rvert = a=30$$ and $$\lvert \overline{CF}\rvert =b= 20,$$ what is the area of $$\triangle CEF?$$
