Area of a parallelogram calculator
Enter the dimensions of a parallelogram and read off its area, its perimeter and the quantities that follow from them.
Area
40m²
- Perimeter
- 28
- Angle between the sides
- 56.4427 degrees
Show the working
- Base = 8
- Perpendicular height = 5
- Slanted side = 6
- Area = 8 * 5 = 40
- Perimeter = 2 * (8 + 6) = 28
- Angle between the sides = 6 > 0 ? deg(asin(clamp(5/6, -1, 1))) : 0 = 56.4427
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- area = base x perpendicular height
- perimeter = 2(base + side)
The height is the perpendicular distance between the parallel sides, not the length of the slanted side.
Lengths are entered in metres by default; switch any field to feet, inches or millimetres and the conversion is exact.
