Area of a parallelogram

For any parallelogram, the area is given by multiplying the length of a base by the perpendicular height from that base to the opposite side. If the parallelogram has base $b$ and height $h$, then $\text{Area} = b \times h$. The height is always measured perpendicular to the base, not along the side.

Important properties

• Area does not depend on the slant of the sides, only on base and height.

• Cutting and rearranging a parallelogram can form a rectangle with the same area.

• If the parallelogram is a rectangle, the formula is the same.

• The base can be any side, as long as the corresponding height is used.
