1. What is the Width of Dodecagon?

The width of a dodecagon is the horizontal distance from the left most edge to the right most edge of the regular dodecagon. It is an important geometric measurement for understanding the dimensions and properties of this 12-sided polygon.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ w = \frac{(2+\sqrt{3}) \times d4}{\frac{(3\sqrt{2})+\sqrt{6}}{2}} \]

Where:

\( w \) — Width of Dodecagon (m)
\( d4 \) — Diagonal Across Four Sides of Dodecagon (m)
\( \sqrt{3} \) — Square root of 3 (approximately 1.732)
\( \sqrt{2} \) — Square root of 2 (approximately 1.414)
\( \sqrt{6} \) — Square root of 6 (approximately 2.449)

Explanation: This formula calculates the width of a regular dodecagon based on the diagonal measurement across four of its sides, using mathematical relationships between the geometric properties of the polygon.

3. Importance of Width Calculation

Details: Calculating the width of a dodecagon is essential for various geometric applications, architectural design, and engineering projects where precise dimensional measurements of polygonal shapes are required.

4. Using the Calculator

Tips: Enter the diagonal across four sides measurement in meters. The value must be positive and greater than zero for accurate calculation.
