See the calculated area instantly and the mathematical formula used for the calculation.
Easily switch between different shapes to calculate areas for various geometric figures.
Rectangle: Area = Length × Width
Circle: Area = π × r² (r = radius)
Triangle: Area = (Base × Height) ÷ 2
Square: Area = Side²
Area is measured in square units. Common units include square meters (m²), square feet (ft²), square inches (in²), and square centimeters (cm²).
Parallelogram: Area = Base × Height
Trapezoid: Area = ((Base₁ + Base₂) × Height) ÷ 2
Area calculations are used in construction, landscaping, interior design, engineering, and many other fields where space measurement is important.
• Use consistent units for all measurements
• Measure carefully and double-check your inputs
• For irregular shapes, break them down into simpler shapes
