plz show the full solution process with clear hand writing thx

2. Using Green's theorem, evaluate / (ey + 4x3y3 ya?) dx + (meg + 31541;2 3x cos y3) dy, 6D where 8D is the boundary of the triangular region D that is dened by portions of the straight lines 3/ = x, y = :v and y = 1, and the integration is in the anti-clockwise direction round 8D. Draw a sketch of the region. Hint: When integrating, exploit the fact that D is symmetric with respect to reection about the y axis
