Formula: Area = base x height (perpendicular). Perimeter = 2 x (base + side).
Compute the area of a parallelogram from base and height, with perimeter from the side length.
Enter the base, height and side length.

A parallelogram is a slanted rectangle with the same area as the rectangle it would make if straightened: base x height. The height must be the perpendicular distance between the base sides, not the slanted side length, which is a common mistake the tool helps you avoid.
Perimeter walks around the shape, so it needs the slanted side length too: 2 x (base + side). Enter the side and the tool reports the perimeter next to the area.
