First, we need to map the coordinates as:
Where the points P, Q, R, and S are equal to (9,2), (-8,2), (-7,7), and (10, 7) respectively.
Then, the area of the parallelogram can be calculated as base times height. So it is equal to:
Base = 9 - (-8) = 9 + 8 = 17
Height = 7 - 2 = 5
Area = Base*Height = 17*5 = 85
