Parallelogram Area Calculator
Find the area of a parallelogram in two ways: base x height, or from two sides and the angle between them. To understand the diagram: base is the bottom side, height is the perpendicular (straight) distance from it, and side is the slant side joined to the base.

How to use
- Enter base and height to get area = base x height.
- Also enter side and angle to see the second area (base x side x sin angle) and the perimeter.
- Both area values should be equal when the angle and height match each other (height = side x sin angle).
Note: Area formula: A = b x h, and A = b x a x sin(theta). Perimeter: P = 2(a + b). The angle is taken in degrees.
