7in. The area of a parallelogram can be found by multiplying the base and the Height. Since the base (9in) and the Area (63in^2) are given we can work back words to find the height of the parallelogram. If you take 63 and divide it by 9, you'd get 7. That means that the height of the parallelogram is 7in. Since the height in question is the same distance from the top to the bottom of the parallelogram, it means the height in question is also 7in
