1. What is the Long Diagonal of Octagon?

The Long Diagonal of an Octagon is the longest straight line that can be drawn between any two opposite vertices of a regular octagon. It passes through the center of the octagon and is an important geometric measurement.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Area \) — Area of the regular octagon (m²)
• \( \sqrt{2} \) — Square root of 2 (approximately 1.4142)

Explanation: This formula derives from the relationship between the area of a regular octagon and its longest diagonal, using the mathematical constant √2.

3. Importance of Long Diagonal Calculation

Details: Calculating the long diagonal is essential in various applications including architectural design, engineering projects, and geometric analysis where precise measurements of octagonal structures are required.

4. Using the Calculator

Tips: Enter the area of the octagon in square meters. The value must be positive and valid. The calculator will compute the long diagonal length.
