Two things to notice/know:

The centroid (intersection of the medians) splits each median in a 2:1 ratio. You can use this to find the length of CP and AP.

Triangle DPE- with sides 1.5, 2, and 2.5- is a right triangle (It's a 3-4-5) with a right angle at P. That makes finding the area of the four triangles inside that trapezoid easy.
