question #2 and Green's Theoremn, show that the area of the quadrilateral with vertices (1, ₁), (x2, Y2), (X3, Y3), (x4, Y4) 15 1 (x1Y2 − x₂Y₁) + (x2Y3 − X3Y2) + (T3Y4 − X4Y3) + (x4Y₁ 2134)]. 2 -x194) Specifically, the quadrilateral is obtained by joining to (x2, Y2), (x2, Y2) to (x3, Y3), (x3, Y3) to (x4, y4), and (x4, y₁) to (x₁, y₁). Make sure you draw a picture.
