# Land Area Calculator

Measure rectangular, triangular or trapezoidal plot areas.

Category: Construction

Plot area depends on the boundary shape and the direction of its measurements. A sloping side is not a triangle's perpendicular height.

Choose the matching simple shape and enter reliable dimensions. Compare the calculated area with surveyed information before using it for a land transaction.

## Inputs and controls

* Shape: Rectangle; Triangle with perpendicular height; Trapezoid with parallel sides
* Measurement unit: Feet; Metres; Inches; Centimetres; Millimetres
* Length or first parallel side. Allowed range: 0.001 to 100000
* Width or perpendicular height. Allowed range: 0.001 to 100000
* Second parallel side. Allowed range: 0.001 to 100000
* Marla definition: 225 sq ft; 250 sq ft; 272.25 sq ft; Custom size
* Custom marla area (sq ft). Allowed range: 1 to 10000

## How to use

* Choose shape and measurement unit. Enter length or first parallel side, width or perpendicular height and second parallel side.

* Choose marla definition. Enter custom marla area.

* Select Calculate estimate. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.


## Why use this tool

The shape choices make common rectangular, triangular and trapezoidal measurements easier to check without combining unrelated formulas.


## Before relying on the result

Use perpendicular height for triangles and trapezoids. Irregular boundaries need surveyed measurements.


## Tool limitations

Use perpendicular height for triangles and trapezoids. Irregular boundaries need surveyed measurements.

## Questions

### Can it measure an irregular property boundary?

Not from a single simple shape. Irregular plots need surveyed dimensions and an appropriate division into measured sections.

### What should I check before using Land Area Calculator?

Check Shape, Measurement unit, Length or first parallel side and Width or perpendicular height. Use the exact units shown beside the controls and replace any example values with your own inputs.
