Use Green's Theorem to evaluate the following line integral. Assume the curve is oriented counterclockwise. A sketch is helpful.
$\oint_C (7y-1.3x^2-5) \cdot dr$, where C is the boundary of the rectangle with vertices (0,0), (5,0), (5,3), and (0,3)
$\oint_C (7y-1.3x^2-5) \cdot dr =$ (Type an exact answer.)
