Hi Hannah!

Did you by chance print the handout before class? I think the week 7 handout and week 7 solutions on the class page are correct. Regardless the problem should be:

In the figure containing right triangle $BCE$ and parallelogram $ABCD$ shown below, $EF = 3$, $EG = 5$ and $BG = 20$. Find the area of the shaded region.
