For this case, what you should see is which lines contain point O.
 We have then that the lines that contain this point are:
 EC
 AD
 BO
 We note that three lines contain point O.
 Therefore, three lines intersect at the same point.

Area of each side triangle is 1/2*8*15 = 60. There are 5 of them so the triangles have surface area 300. the pentagon's area 1/2*apothegm*sidelength*sides = 1/2*5.5*8*5 = 110. The total area is therefore 300+110 = 410
