This tool calculates the total square footage of an irregular shape based on your input measurements.

## How to Use the Square Footage Calculator for Irregular Shapes

To use this calculator, input the lengths of all four sides of your irregular shape in the fields provided. Additionally, you must provide the interior angles between side 1 & side 2, and side 3 & side 4. The angles must be specified in degrees.

## Explanation of Calculation

The result is calculated using the Brahmagupta formula, which is an extension of Heron’s formula for irregular quadrilaterals. This formula computes the area based on the lengths of the sides and the interior angles you’re providing. The area is given in square feet (ft²).

## Limitations

This calculator is designed for quadrilateral shapes with known side lengths and interior angles. It assumes the shape is a simple quadrilateral without any crossing sides.
