Geometry Level pending

If the two adjacent vertices of a parallelogram are $$A=(-2,4)$$ and $$B=(-1,3)$$ and the midpoint of the line joining the midpoint of opposite sides of the parallelogram lie on the positive $$x$$-axis, find the coordinates of the other vertices if the area of the parallelogram is 12 .

If these coordinates can be expressed as $$(x_1, y_ 1)$$ and $$(x_2, y_2)$$, then submit $$x_1 + x_2 + y_1 + y_2$$ as your answer.
