How to use the irregular land area calculator
The irregular land area calculator is an essential tool for property owners, real estate agents, architects, and engineers who need to calculate the area of land that doesn't have a perfectly regular shape. This calculator uses a simplified method that provides a good approximation of the actual land area, considering the measurements of the four main sides.
- Accurately measure the land dimensions: front, back, right side, and left side
- Enter the obtained values in the corresponding fields, using meters as the unit of measurement
- Make sure to use a period (.) as the decimal separator if needed
- Click the 'Calculate' button to get the result in square meters and hectares
- Use the share or print buttons to save or send the result
Formula for calculating irregular land area
The calculation of an irregular land area is performed using a formula that considers the average of the parallel measurements of the land. This method is known as the 'Parallel Measurements Average Method' and is widely used in surveying and topography for lands that have minor irregularities.
Area = ((Front + Back) × (Right Side + Left Side)) ÷ 4
This formula considers that:
- The average of front and back represents the average width of the land
- The average of the sides represents the average length of the land
- The multiplication of these averages provides a satisfactory approximation of the total area
Practical calculation examples
For better understanding, let's analyze some practical examples of area calculation:
- Land with front of 12m, back of 10m, right side of 25m and left side of 25m. Area = ((12 + 10) × (25 + 25)) ÷ 4 = 275m²
- Land with front of 15m, back of 15m, right side of 30m and left side of 32m. Area = ((15 + 15) × (30 + 32)) ÷ 4 = 465m²
- Land with front of 20m, back of 18m, right side of 40m and left side of 42m. Area = ((20 + 18) × (40 + 42)) ÷ 4 = 779m²
Frequently Asked Questions (FAQ)
What is irregular land?
Irregular land is land that doesn't have a perfectly defined geometric shape, such as a rectangle or square. It may have sides with different measurements, angles that aren't right angles (90°), or small variations in its perimeter.
How accurate is this calculation method?
This method provides a good approximation for lands with moderate irregularities. For very irregular lands or those with very complex shapes, it's recommended to hire a surveying professional for a more accurate measurement.
When should I use this calculator?
This calculator is ideal for initial estimates, preliminary assessments, and situations where the land has an approximately trapezoidal or rectangular shape with small variations. It's very useful for real estate agents, property owners, and professionals who need a quick area estimate.
How to convert square meters to hectares?
One hectare (ha) equals 10,000 square meters (m²). To convert from m² to hectares, simply divide the value in square meters by 10,000. Our calculator performs this conversion automatically for your convenience.
