Area = Length x width
It's the same as the area for a rectangle - base times height. If you think about it, a parallelogram is a rectangle with two triangles on either side - one with its base on top, one with its base on bottom. Through various identities, we know that these two triangles are congruent. So the area is the sum of the small rectangle plus the two triangles, which ends up being base times height.

The area formula for the parallelogram is related to the area formula for a rectangle because you can make the parallelogram into a rectangle to find the area.
The formula to find the surface area of a parallelogram is Base*Height.
Area = length*perpendicular height
It is the length of the base multiplied by the height.
The formula for the volume of a parallelogram prism is V = Bh, where B is the base area of the parallelogram and h is the height of the prism. The formula for the surface area of a parallelogram prism is SA = 2B + Ph, where P is the perimeter of the base parallelogram. The base area of a parallelogram can be calculated as A = b * h, where b is the base length and h is the height of the parallelogram.
