Parallelogram Area Formula
The area of a parallelogram is calculated by multiplying the base by the perpendicular height.
Area = Base × Height
How to Calculate Parallelogram Area
- Measure the base of the plot.
- Measure the perpendicular height between the two parallel sides.
- Make sure both measurements use the same length unit.
- Multiply the base by the perpendicular height.
- Convert the result to your required square area unit.
Example Calculation
Suppose a parallelogram-shaped plot has a base of 20 metres and a perpendicular height of 10 metres.
Area = 20 × 10
Area = 200 square metres
Using This Calculator for Land Measurement
This calculator is useful when a plot has two pairs of parallel sides and its perpendicular height can be measured. It can help estimate the geometric area before converting the result into another square measurement unit.
For irregular land boundaries, the parallelogram formula should not be used unless the measured section actually forms a parallelogram.
Common Mistakes
- Using a slanted side as the height instead of the perpendicular height.
- Mixing metres and feet in the same calculation.
- Entering the diagonal instead of the base.
- Using this formula for an irregular plot boundary.
When Not to Use This Calculator
If the plot is rectangular, you can use the Rectangle Area Calculator.
If the plot is triangular, use the Triangle Area Calculator.
Frequently Asked Questions
What is the formula for parallelogram area?
The formula is Area = Base × Height, where height means the perpendicular distance between the parallel sides.
Can I use a slanted side as the height?
No. The height must be the perpendicular distance between the two parallel sides.
Can I calculate the area in square feet?
Yes. Enter the dimensions in a supported length unit and select square feet as the result unit.
Is this suitable for an irregular land plot?
No. The formula is intended for parallelogram-shaped geometry. Irregular plots require a different measurement method.
Land Measurement Note
This calculator provides geometric area only. Local land records and traditional land units can vary by state and region, so official records should be used when legal land-area accuracy is required.
