If the area is 64 inches squared, what is the missing length ?
Igoryamba
The area of a parallelogram is equal to the base multiplied by the height. Since we can see that this is a parallelogram (because of the two pairs of parallel sides), we now know how to find the area. Since we already know the height and the area, we can substitute their values into the formula to solve for the base.

8 * (the base) = 64

Divide each side by 8 to figure out the length of the base

the base = 8 in.
