SOLUTION:
Given that the coordinates of a parallelogram are Q(3, -2), R(7, -2), S(9,3), and T(5,3), we are to find the area of the parallelogram.
To find the base QR;
Q(3, -2) and R(7, -2)
Base = 7 - 3 = 4 units
To find the height of the Parallelogram;
T(5, 3) and Q(3, -2)
Height = 3 - (-2) = 3 + 2 = 5 units
The formula to calculate the area of a parallelogram is given as;
Area of parallelogram = base × height square units.
Area = 4 units x 5 units
Area = 20 units squared (Option B).
