Rectangle/Circle/Triangle area calculation and unit conversion
This calculator computes the area of various shapes including rectangles, circles, triangles, trapezoids, and parallelograms. Enter known parameters to quickly calculate area, with support for unit conversion.
Area calculation is commonly used in renovation, real estate, land surveying, and agriculture. This tool supports square meters, square feet, acres, hectares, and other area units.
Common shape area formulas:
1. Rectangle: Length ร Width Example: Living room 5m ร 4m = 20 m^2
2. Circle: ฯ ร Radius^2 โ 3.14159 ร r^2 Example: Radius 3m = 28.27 m^2
3. Triangle: Base ร Height รท 2 Example: Base 6m, Height 4m = 12 m^2
4. Trapezoid: (Top + Bottom) ร Height รท 2 Example: Top 3m, Bottom 5m, Height 4m = 16 m^2
5. Parallelogram: Base ร Height Example: Base 6m, Height 3m = 18 m^2
6. Sector: ฯ ร Radius^2 ร Angle รท 360
Unit conversions: - 1 m^2 = 10.764 ft^2 - 1 hectare = 10,000 m^2 โ 2.471 acres - 1 acre โ 4,047 m^2
