How to Use the Octagon Calculator
To use this octagon calculator, simply enter the length of a side of the octagon into the first field, and then click on the “Calculate” button. The calculator will compute and display the area and perimeter of the octagon.
How the Calculator Works
The calculator uses the following formulas:
- Area (A) = 2 * (1 + √2) * sideLength2
- Perimeter (P) = 8 * sideLength
It calculates the area by taking the length of the side, squaring it, and then multiplying by 2 * (1 + √2), which is a constant for octagons. The perimeter is calculated by multiplying the side length by 8.
Limitations
This calculator assumes a regular octagon, where all sides and angles are equal. It does not account for irregular octagons. Ensure that you input a positive number for the side length. It may not accurately calculate very large or very small numbers due to limitations in JavaScript’s floating-point arithmetic.
