Need to use 2 of the dx type integrals since the bottom boundary is made up of both a parabola and a line. Need only 1 of the dy type integrals since the left and right boundary does not change.

Simpler Directions of Integration: When to use a dx verses a dy integral. 4. Need to use two integrals because the left and right curves change.
