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.
Frequently Asked Questions (FAQ)
What does the parallelogram area calculator find?
The area of a parallelogram two ways: base times height, or from two sides and the angle between them. It also gives the perimeter.
What do base and height mean here?
Base is the bottom side; height is the perpendicular distance between the two bases, not the slanted side.
When should I use the side-and-angle method?
Use it when you know the two side lengths and the angle between them instead of the perpendicular height. The area is then side a times side b times the sine of the angle.
What units should I enter?
Use the same unit, such as cm or inches, for every side. The area answer is in square units and the perimeter in the same unit.
