Find work done by F= around the triangle from (0,0) to (1,1), to (-1,1), and back to (0,0). How should I begin to do this beast? It seems like I should use Green's thm, but how?

Question

Find work done by F=<√(lnx)−y,x^2+e^(tany)> around the triangle from (0,0) to (1,1), to (-1,1), and back to (0,0).
How should I begin to do this beast?

According to green's thm, it seems I need to find Nx-My, which I found to be 2x+1
So, $$\int\limits_{}^{}\int\limits_{}^{} (2x+1)da$$ but if the initial and end points are (0,0) then that makes no sense.

I originally had the $$\int\limits_{0}^{1}\int\limits_{-1}^{1}2x+1 dxdy$$ and my professor wrote "your H.S. region is a rectangle." Would that help?
