Answer:
h = 10 13/14 units
Explanation:
You want the height from the side of length 14 of a parallelogram with side length 17 and height 9.
Area
The area of a parallelogram is the same, no matter which side is used as the "base". This means ...
A = bh = 17(9) = 14(h)
h = 17·9/14 = 10 13/14 . . . . units
