# Parallelogram A **parallelogram** is a [[quadrilateral]] in which opposite sides are [[parallel lines|parallel]]. ## Area To calculate the area of a parallelogram, pick one side as its "base" and measure the [[perpendicular distance]] from this base to its opposite side. The area of the parallelogram is the product of the length of the base and this distance. [[!redirects parallelograms]] [[!redirects area of a parallelogram]]
