# How To Work Out The Area Of A Parallelogram?

## How do you find the area for a parallelogram?

To find the area of a parallelogram, multiply the base by the height.

The formula is: A = B * H where B is the base, H is the height, and * means multiply.

The base and height of a parallelogram must be perpendicular.

## How do you find the missing length of a parallelogram?

Ex: Determine the Length of a Missing Side Given the Perimeter

## How do you find the area of a parallelogram without height?

If you know the slant height and the angle between the slant height and the base you can use trigonometry, sin, to find the height. Or if you know the small segment that forms a right triangle and the slant height, you can use the pythagorean theorem to find the height.

## How do you find the missing height of a parallelogram?

To find the missing base, you simply divided the area by the given height. This will work the same way if you are looking for the height. To find the missing height, divide the area by the given base. Consider this parallelogram where height is the missing dimension.
