Area
50.0000 units²
  • Base10
  • Height5

Step-by-step

  1. Area = b × h = 10 × 5 = 50.0000.

How to use this calculator

  • Enter the base.
  • Enter the perpendicular height (not the slant side).

About this calculator

A parallelogram has two pairs of parallel sides. Its area is base × perpendicular height — the same formula as a rectangle, because slanting the rectangle doesn't change the area (the missing right triangle from one side reappears on the other).

Frequently asked

Because area is preserved by the slant — a parallelogram is a rectangle that's been pushed sideways. The actual side length doesn't enter the area formula.
