A parallelogram is a quadrilateral with two pairs of parallel sides.
The side upon which the parallelogram rests is called its base, while the length of a perpendicular line from the base to the opposite side is called the height. (See: Parts of a Quadrilateral.)
To find the area of a parallelogram, you can simply multiply the base with the height.
A = b x h
You can find HERE a video that gives a very clear explanation — using Montessori geometry materials — for why the formula for the area of a parallelogram is the same as the formula for the area of a rectangle.
In fact, rectangles, squares, and rhombuses are special types of parallelograms. (See: Quadrilateral Family Tree.)
