Answer:
x=15 yards
Explanation:
The formula for the area of a parallelogram is :

The formula for the length of the base is :

To work out the value of x you would divide the area of 120 by the height of 8, this gives you 15 yd. This is because the formula is base*height and so by dividing the the area by the height we are rearranging the formula to
.
1) Divide 120 by 8.
