Area Calculator – Find Area of Any Geometric Shape Instantly
The Area Calculator is a powerful tool that helps you determine the surface area of various geometric shapes such as squares, rectangles, triangles, circles, trapezoids, parallelograms, ellipses, and more. Whether you’re a student, engineer, architect, or DIY enthusiast, this calculator is your go-to tool for precise area measurements in seconds.
What is Area?
In mathematics, area is the amount of space covered by a two-dimensional shape or surface. It is measured in square units such as square meters (m²), square feet (ft²), square inches (in²), etc.
Supported Shapes in Our Area Calculator
- Square
- Rectangle
- Triangle
- Circle
- Parallelogram
- Trapezoid
- Ellipse
- Sector
How to Use the Area Calculator
- Select the shape you want to calculate the area for.
- Enter the required dimensions (length, width, base, height, radius, etc.).
- Choose your preferred unit (e.g., meters, feet, inches).
- Click on "Calculate Area" to get the result instantly.
Area Formulas for Different Shapes
Square
Area = side × side
Rectangle
Area = length × width
Triangle
Area = 0.5 × base × height
Circle
Area = π × radius²
Parallelogram
Area = base × height
Trapezoid
Area = 0.5 × (base1 + base2) × height
Ellipse
Area = π × semi-major axis × semi-minor axis
Sector (of a circle)
Area = (θ / 360) × π × r²
Where θ is the central angle in degrees, and r is the radius.
Example Calculations
Example 1: Area of a Rectangle
If a rectangle has a length of 8 meters and a width of 5 meters:
Area = 8 × 5 = 40 m²
Example 2: Area of a Circle
If the radius of a circle is 7 inches:
Area = π × 7² ≈ 3.1416 × 49 ≈ 153.94 in²
