Parallelogram Area Calculator
Calculate parallelogram area from base and height, two sides with the included angle, diagonals with their angle, or two sides and one diagonal.
Parallelogram area from the values you know
English search results for this intent expect more than a single base-height formula. This calculator keeps base and height first, then adds sides with included angle, diagonals with their included angle, and two sides with one diagonal.
A is area; b is the base; h is the perpendicular height.
a and b are adjacent sides; theta is the included angle.
d_1 and d_2 are diagonals; phi is the angle between them.
Supported input modes
| Known values | What the calculator returns |
|---|---|
| Base and height | Area directly; side length is optional for perimeter and diagonals. |
| Two sides and included angle | Area, height, perimeter, both diagonals, and angles. |
| Two diagonals and angle | Area, side lengths, height, perimeter, and angles. |
| Two sides and one diagonal | The included angle first, then area and related values. |
