Centroid, moment of inertia of composite area

For the area shown determine
  1. The area
  2. The moment of inertia with respect to the line a-a (bottom).
  3. The moment of inertia with respect to the axis b-b (top) using the results from above plus the parallel axis theorem (be very careful !!).
