Step-by-step
- 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.
