I got 8.3 for the apothem of the pentagon. Your setup seems to be right. Also you need to pay more attention to the form of the answers in both questions.

\[\tan 36=\frac{6}{b}\] \[b \tan 36=6\] \[b=\frac{6}{\tan 36}=8.3\]

Therefore the area of the pentagon = 5(1/2)(12)(8.3)=247.7

The pyramid is composed of the base which is a pentagon and 5 sides which are 5 congruent triangles. If it said lateral surface area it would be just the 5 triangles but it says surface area so we have to assume it means all of the surfaces.
