About Our 2D Shape Area Calculator
Our 2D Shape Area Calculator is a versatile tool designed to quickly compute the area of common geometric shapes. Whether you're a student learning geometry, a professional working on spatial calculations, or just curious about areas, this calculator makes finding areas simple and accurate.
Supported Shapes and Formulas
- Circle: Area = πr² (where r is the radius)
- Square: Area = s² (where s is the side length)
- Rectangle: Area = l × w (where l is length and w is width)
- Triangle: Area = ½ × b × h (where b is base and h is height)
- Trapezoid: Area = ½ × (a + c) × h (where a and c are parallel sides and h is height)
- Parallelogram: Area = b × h (where b is base and h is height)
Key Features:

Frequently Asked Questions
What units are used for the area calculations?
Our calculator works with any consistent unit system. If you enter measurements in centimeters, your area will be in square centimeters (cm²). Similarly, if you use inches, your result will be in square inches (in²). Just make sure all measurements for a single calculation use the same unit.
How accurate are the calculations?
Our calculator provides results with high precision. For circles and other shapes involving π (pi), we use a precise value of π to ensure accuracy to several decimal places. The results are rounded to two decimal places for readability.
Can I calculate the area of irregular shapes?
This calculator is designed for standard geometric shapes. For irregular shapes, you can often break them down into combinations of basic shapes (rectangles, triangles, etc.), calculate each area separately, and then add them together for the total area.
