parallelogram
**
is a quadrilateral whose opposite sides are parallel.

To find the area of a parallelogram, make it into a rectangle.

From this, we see that the area of a parallelogram is the same as the area of a rectangle. The area of a parallelogram is
. The height of a parallelogram is always perpendicular to the base.
*
This means that the sides are not the height.
