What Is a Parallelogram Calculator?

A parallelogram is a four-sided shape with two pairs of parallel sides, such as a rhombus or a slanted rectangle. This calculator finds its area from the base and height, and its perimeter from the base and side length.

Formulas

Area: A = base × height
Perimeter: P = 2 × (base + side)

How to Use This Calculator

Enter the base length and the perpendicular height.
Enter the slanted side length if you also want the perimeter.

Worked Example

A parallelogram has a base of 10 cm, a height of 6 cm, and a side length of 7 cm. The area is 10 × 6 = 60 cm². The perimeter is 2 × (10 + 7) = 34 cm.

Common Uses

Useful for calculating land area on slanted plots, material needed for parallelogram-shaped tiles or panels, and geometry homework involving quadrilaterals.
