Hm.. it seems that a figure of polygon ABCDE would help you a lot.

Oh, I answered this the other day.

anonymous · Answer

You just add them up 15.9 + 19.6 + 17.5

anonymous · Answer

The triangles make up the whole figure.

Yep, I was correct, you just add them up because the triangles make up the whole figure. So their areas combined will give us the total area of the entire figure.
