For week 5, 5.26, what does it mean by find [ABCDEF]

the area?

the perimeter?

neither?

Also, for 5.29, in my drawing of the diagram, P and N are on the same point, so the problem doesn't make sense. If I am making a mistake with my diagram, please help me and show me a picture that is accurate so I can see my mistake.

My teacher is professor David, btw

Whenever we use "$[ABC]$", it means "the area of polygon $ABC$".


For problem 29, note some of the sides of the pentagons will be shared and they all share one vertex. 

Hint: What is the sum $\angle NAE + \angle EAR + \angle RAP$ equal to?
