1. What is Perimeter?

The perimeter is the total distance around a two-dimensional shape. It's calculated by adding up the lengths of all the sides of the shape.

2. How Does the Calculator Work?

The calculator uses the perimeter formula:

Where:

• \( P \) — Perimeter (length units)
• \( side_i \) — Length of each side (length units)
• \( n \) — Number of sides

Explanation: The calculator first asks for the number of sides, then prompts for each side's length, and finally sums all lengths to get the perimeter.

3. Importance of Perimeter Calculation

Details: Perimeter calculations are essential in construction, land surveying, fencing, and any project requiring measurement of boundaries.

4. Using the Calculator

Tips: Enter the number of sides (minimum 3), then input each side's length. All side lengths must be positive numbers.

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: Can this calculator handle curved shapes?
A: No, this calculator is designed for polygons. For circles, use the circumference formula (2πr).

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

Q4: Does the order of side lengths matter?
A: No, the perimeter is the same regardless of the order you enter the sides.

Q5: What's the maximum number of sides allowed?
A: The calculator accepts up to 20 sides, which covers most practical applications.
