What is the 2D Shape Area Calculator?

The 2D Shape Area Calculator is a tool designed to help students, engineers, and general users quickly find the area of common 2D shapes such as circles, rectangles, triangles, trapezoids, and ellipses. By entering the necessary dimensions, the calculator instantly computes the area using the correct formula, providing an accurate result without the need for manual calculations. This ensures clarity, saves time, and helps avoid mistakes while studying or working on geometric problems.

How to Use:

1. Choose Shape: Select the shape you want to calculate from the dropdown menu.
2. Enter Required Dimensions: Input the measurements shown (e.g., radius for circle, width and height for rectangle).
3. Click “Calculate Area”: The calculator computes and displays the area in square units.
4. Formulas Reference:
   • Circle: π × r²
   • Rectangle: width × height
   • Triangle: 0.5 × base × height
   • Trapezoid: 0.5 × (a + b) × height
   • Ellipse: π × a × b
