How to use the parallelogram area calculator
Find area and perimeter of a parallelogram. Enter base, side, angle between sides in the fields above; the area, perimeter, height are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- b — Base
- s — Side
- th — Angle between sides (°)
Worked example
With base = 10, side = 6, angle between sides = 60 °, the calculator gives area ≈ 51.96152; perimeter ≈ 32; height ≈ 5.196152.
Frequently asked questions
What is the formula for the parallelogram area calculation?
Area = b × s × sin(th). Perimeter = 2 × (b+s). Height = s × sin(th). Here b is base, s is side, th is angle between sides (°).
What inputs do I need for the parallelogram area calculator?
You need base, side, angle between sides in °. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
