1. What is Perimeter?

Perimeter is the total distance around a two-dimensional shape. It's calculated by summing the lengths of all sides of the shape.

2. How Does the Calculator Work?

The calculator uses the perimeter formula:

Where:

• \( P \) — Perimeter in length units
• \( \sum \) — Sum of all side lengths

Explanation: The calculator adds up all the side lengths you provide to give the total perimeter.

3. Importance of Perimeter Calculation

Details: Perimeter calculations are essential in construction, landscaping, fencing projects, and any application where you need to know the boundary length of a shape.

4. Using the Calculator

Tips: Enter all side lengths separated by commas. For regular polygons, you can enter the same value multiple times or multiply one side by the number of sides.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between perimeter and area?
A: Perimeter measures the distance around a shape, while area measures the space inside it.

Q2: How do I calculate perimeter for a circle?
A: For circles, we use circumference (C = 2πr) rather than perimeter.

Q3: What units should I use?
A: Use consistent units for all sides (meters, feet, inches, etc.).

Q4: Can I calculate perimeter with only some sides known?
A: For irregular shapes, you typically need all side lengths. For regular polygons, you only need one side length.

Q5: How accurate is this calculator?
A: It's as accurate as the measurements you input, with results rounded to 2 decimal places.
