- Perpendicular height: Shortest perpendicular distance between the parallel bases.
GEOMETRY / BASE AND HEIGHT
Parallelogram Calculator
Calculate parallelogram area and perimeter from base, slanted side, and perpendicular height while validating their physical relationship.

Calculation path
The base is multiplied by perpendicular height for area, while two copies of the base and side form perimeter.
Calculation path
Area = base x perpendicular height; perimeter = 2 x (base + side).

Choose the maximum decimal places shown. This does not increase source accuracy.
Height must not exceed the adjacent side and must be perpendicular rather than measured along the slant.
