Perimeter Calculator
Welcome to the Perimeter Calculator! This intuitive tool allows you to easily compute the perimeter (or circumference for circles) of common geometric shapes. Whether you’re a student, teacher, or just curious, enter the dimensions and get instant results.
How to Use
Step 1: Select the shape from the dropdown menu.
Step 2: Enter the required dimensions in the fields that appear.
Step 3: Click the “Calculate Perimeter” button to see the result.
Note: For circles, this calculates the circumference. All inputs must be positive numbers.
Perimeter Calculator
Perimeter is the total distance around a shape. For circles, this is called the circumference. Use the Pacy Perimeter Calculator to quickly calculate the perimeter of squares, rectangles, triangles, and circles. Perfect for students, teachers, and professionals.
How to Use the Calculator
- Select your shape: square, rectangle, triangle, or circle.
- Enter the required dimensions (sides or radius).
- Click the “Calculate Perimeter” button.
- View the result instantly.
Perimeter Formulas
- Square: Perimeter = 4 × side
- Rectangle: Perimeter = 2 × (length + width)
- Triangle: Perimeter = side1 + side2 + side3
- Circle (Circumference): C = 2 × π × radius
Example Calculations
| Shape | Dimensions | Calculation | Result |
|---|---|---|---|
| Square | Side = 5 | 4 × 5 | 20 |
| Rectangle | Length = 10, Width = 5 | 2 × (10 + 5) | 30 |
| Circle | Radius = 7 | 2 × π × 7 | 43.98 |
| Triangle | Sides = 3, 4, 5 | 3 + 4 + 5 | 12 |
