The area of a parallelogram is length x height.
The answer would be C. A = 12 • 8
X is equal to -11/6 or -1.8333333333..................................
We know, 3 feet = 1 yard.
We have to convert feet to yards to calculate the ratio so that the final answer doesn't have any unit.
Therefore, 21 feet =
= 7 yards
Thus, the ratio

The fraction
is already in its simplest form.
Therefore, the given ratio as a fraction in the simplest form without any units is
