Finding the area of a parallelogram is very similar to finding the area to that of a rectangle.
The equation for area A is
where b is the base length and h is the height.
We are given a base length of 15 inches, and the height of the parallelogram is 7 inches (not 9 inches).
The area of the parallelogram is 105 square inches. Let me know if you need any clarifications, thanks!
