The Parallelogram Area Calculator computes the area of a parallelogram using two common methods:

Base × Height — enter the base length and the corresponding height.

Sides × sin(angle) — enter two adjacent side lengths aaa and bbb and the included angle θθθ in degrees; the formula is Area=a×b×sin⁡(θ)\text{Area} = a \times b \times \sin(\theta)Area=a×b×sin(θ).
Choose the method, enter values, and click Calculate — the result appears instantly with high precision. Ideal for geometry homework, engineering sketches, and quick checks.
