Formula for the area of a regular hexagon
The area of a regular hexagon is calculated from side L:
A = (3√3 / 2) × L² ≈ 2.598 × L²
A regular hexagon can be divided into 6 equilateral triangles with side L, each with area (√3/4) × L². The sum of the six triangles gives the formula above.
Practical examples
| Side (L) | Area (A ≈ 2.598 × L²) |
|---|---|
| 1 m | 2.598 m² |
| 5 cm | 64.952 cm² |
| 10 m | 259.808 m² |
| 3.5 cm | 31.827 cm² |
| 8 mm | 166.277 mm² |
Frequently asked questions
What is the formula for the area of a regular hexagon?
The area is A = (3√3 / 2) × L², where L is the side length. For example, side 5 cm: A = (3√3 / 2) × 25 ≈ 64.95 cm².
Why can a regular hexagon be divided into 6 triangles?
Because all sides and internal angles (120°) are equal. Connecting the center to the vertices gives 6 equilateral triangles with side L, each with area (√3/4) × L². Adding the six: A = 6 × (√3/4) × L² = (3√3/2) × L².
What is the apothem of a regular hexagon?
The apothem is the distance from the center to the midpoint of a side, equal to a = L × √3 / 2. The area can also be calculated as A = 3 × L × a.
Can I use a comma instead of a decimal point?
Yes. This calculator accepts both comma and period as the decimal separator.
