How to Use This Calculator
- Enter the Base (one of the parallel sides) and the Height (perpendicular distance between the parallel sides).
- Enter the Side length (the non-base side) to compute the perimeter.
- Area = base × height (not base × side — height must be perpendicular to the base).
- Perimeter = 2 × (base + side), since opposite sides of a parallelogram are equal.
- A rectangle is a special parallelogram where height equals side; a rhombus has all sides equal.
- All inputs must be positive; if only area and base are known, height = area / base.
How the result changes with Base
| Base | Area |
|---|---|
| 1,000 | 5,000 |
| 3,500 | 17,500 |
| 6,500 | 32,500 |
| 9,000 | 45,000 |
What each input means
- Base
- Length of the base.
- Height
- Height of the parallelogram.
- Side Length
- Length of the side (defaults to base if not specified).
