field F = , use Green's Theorem to find the work done in a particle traveling along a triangular path in the first quadrant of the xy-plane such that it starts at the origin (0,0), proceeds along the x- axis to the point (2,0), then diagonally along a straight line to the point (0,2), and finally back down to the origin along the y-axis.
