1. What is Perimeter of Equilateral Triangle?

The perimeter of an equilateral triangle is the total length around the triangle. Since all three sides are equal in an equilateral triangle, the perimeter is simply three times the length of one side.

2. How Does the Calculator Work?

The calculator uses the perimeter formula:

Where:

• \( P \) — Perimeter (units)
• \( s \) — Length of one side (units)

Explanation: The formula multiplies the side length by 3 since all sides are equal in an equilateral triangle.

3. Importance of Perimeter Calculation

Details: Calculating perimeter is essential in geometry, construction, and various engineering applications where boundary measurements are needed.

4. Using the Calculator

Tips: Enter the side length in any unit of measurement. The result will be in the same units. Value must be positive.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between perimeter and area?
A: Perimeter measures the total boundary length, while area measures the space enclosed within that boundary.

Q2: Does this formula work for other triangles?
A: No, this specific formula only works for equilateral triangles. Other triangle types require adding all three side lengths.

Q3: What if I only know the height?
A: You can calculate the side length first using height formula (h = (√3/2) × s), then use perimeter formula.

Q4: Can I use this for 3D objects?
A: No, this is for 2D equilateral triangles. For 3D objects like triangular prisms, you need different formulas.

Q5: What units should I use?
A: Any consistent length unit (meters, feet, inches, etc.). The result will be in the same units as input.
