Understanding the Area Calculator
This calculator provides a simple way to find the surface area of common shapes. It's useful for home improvement projects, landscaping, or any situation where you need to measure a two-dimensional space.
How It Works
The calculator uses standard geometric formulas for each shape:
- Rectangle:
Area = Length × Width - Circle:
Area = π × Radius² - Triangle:
Area = 0.5 × Base × Height
Units
You can enter your dimensions in various units (feet, meters, or inches). The calculator will automatically convert the result into square feet (ft²), square meters (m²), and square inches (in²) for your convenience.
For three-dimensional calculations, see our Volume Calculator.
