The area of a parallelogram can be calculated using the formula $$A=bh,$$ where $b$ represents the lengths of the parallelogram's base and $h$ its height.

The area of a parallelogram can also be calculated using the length of two non-parallel sides. If two non-parallel sides have the lengths $a$ and $b$ respectively the area of the parallelogram is given by $$A=ab\cdot \sin (\theta ),$$ where $\theta$ is the measure of the angle between the sides.
