1. What is Polygon Perimeter?

The perimeter of a polygon is the total distance around the outside of the polygon. For a regular polygon (all sides equal), it's simply the number of sides multiplied by the length of one side.

2. How Does the Calculator Work?

The calculator uses the perimeter formula:

Where:

• \( P \) — Perimeter (length units)
• \( n \) — Number of sides (integer ≥ 3)
• \( s \) — Length of each side (length units)

Explanation: The formula works for any regular polygon where all sides are equal length.

3. Importance of Perimeter Calculation

Details: Perimeter calculations are fundamental in geometry, construction, landscaping, and various engineering applications where boundary measurements are needed.

4. Using the Calculator

Tips: Enter the number of sides (must be 3 or more) and the length of each side. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Does this work for irregular polygons?
A: No, this calculator is for regular polygons only. For irregular polygons, you would need to sum all the individual side lengths.

Q2: What's the minimum number of sides?
A: A polygon must have at least 3 sides (triangle). The calculator enforces this minimum.

Q3: Can I use decimal values for side length?
A: Yes, side length can be any positive number including decimals.

Q4: What units should I use?
A: Any consistent length unit can be used (meters, feet, inches, etc.). The result will be in the same units as your input.

Q5: Does this work for 3D shapes?
A: No, this is for 2D polygons only. For 3D shapes you would calculate the perimeter of each face separately.
