Hello. Please include answers to the following questions below with all the steps, even small steps as well. It would be greatly appreciated. These are university-level calculus 3 level questions. I am very very confused as to how to even go about solving these homework questions.

Thank you.

1). Use Green's theorem to calculate the work done by force F (n, 9 ) = ( 20 2 - 5 y )i + ( 3 x - 2 5y ) on a particle that is moving counter clockwise around triangle with Vertices (0,0) ( 4, 0 ) and (0, 4 ).
