Answer:
The side with 64 units cannot be the height of the parallelogram and the side with 8 units can be the side of the parallelogram.
Explanation:
Area of parallelogram= 40 sq units
One side of the parallelogram= 64 units
∴ the dimension with 64 units cannot be the height of the parallelogram because the side is more than area. When multiplying with the other side, the area will be more than 40.
Other side of the parallelogram= 8
∴ the dimension with 8 units is possible and it can be the height of the parallelogram because the side is less than area. When multiplying with the other side, the area will be 40.
