Parallelogram Calculator
Calculate area using perpendicular height and perimeter using side lengths.
Your numbers
Area
Use consistent units. The result follows the assumptions you enter.
Scenario comparison
Up to three snapshots in this tab. Loading one replaces the current inputs.
Formula
Use A = bh and P = 2(b+s). b is base, h is perpendicular height, and s is the adjacent side, all in the same length unit. A is area and P is perimeter.
Calculate area using perpendicular height and perimeter using side lengths.
Worked example
- Base (m)
- 6
- Perpendicular height (m)
- 4
- Adjacent side (m)
- 5
- Area
- 24 m²
- Perimeter
- 22 m
Scope and limitations
Use consistent units. The result follows the assumptions you enter.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
