The formula for area of a parallelogram is A = bh, where b is the base length and h is the height. The base of the parallelogram with vertices (-4, 2), (1, 6), (15, 6), and (10, 2) is 14 units, and the height is 4 units (see attachment). Let's plug in our numbers and solve for the area.
A = bh
A = 14(4)
A = 56
Answer:
The area of a parallelogram is 56 units squared.
