Answer:
The height of the parallelogram is 3 yards.
Explanation:
A parallelogram has a base of 7 yards, and an area of 21 square yards.
The formula for the area of a parallelogram is A = bh.
So, to find h (the height), that formula becomes h = A/b
h = 21/7
h = 3
The height of the parallelogram is 3 yards.
(Work Check:
A = bh
A = 7 * 3
A = 21)
