The calculator supports 5 shapes: Square, Rectangle, Circle, Triangle, and Trapezoid. Each shape has its specific formula and required inputs.
Metric units (meters, centimeters, millimeters) and Imperial units (feet, inches). Results show as unit² (e.g., m², ft², in²).
Calculations use high-precision mathematical operations. For circles, π is used to 15 decimal places. Results are accurate for practical applications.
This calculator handles standard geometric shapes. For irregular shapes, you may need to break them down into these basic shapes and sum the areas.
