Area Calculator

Calculate the area of various common geometric shapes.

Result will be in square units (e.g., m², ft²).

Select shape and enter dimensions.

Calculating the Area of Common Shapes

Finding the area – the amount of space a two-dimensional shape occupies – is a fundamental concept in geometry with numerous practical applications, from home improvement projects (calculating paint or flooring needed) to engineering and design.

How to Use

  1. Select the Shape you want to calculate the area for from the dropdown menu.
  2. The required input fields for that shape's dimensions will appear.
  3. Enter the dimensions (length, width, radius, base, height, etc.) for your shape.
  4. Select the Unit your dimensions are measured in (e.g., meters, feet).
  5. Click "Calculate Area".

The calculator will display the calculated area in the corresponding square units (e.g., m², ft²).

Common Area Formulas

  • Rectangle/Square:** Area = Length × Width
  • Triangle:** Area = 0.5 × Base × Height
  • Circle:** Area = π × Radius² (where π ≈ 3.14159)
  • Trapezoid:** Area = 0.5 × (Base1 + Base2) × Height
  • Parallelogram:** Area = Base × Height
  • Ellipse:** Area = π × Semi-axis a × Semi-axis b

Ensure all dimensions are entered in the same unit for an accurate result.
