This regular polygon perimeter reference table shows the perimeter for a range of number of sides values, assuming a side length of 10. Every figure is computed with the same engine that powers our Regular Polygon Perimeter Calculator, so the numbers are exact.
| Number of sides | Perimeter |
|---|---|
| 3 | 30.0000 |
| 4.5 | 45.0000 |
| 6 | 60.0000 |
| 9 | 90.0000 |
| 12 | 120.0000 |
| 18 | 180.0000 |
| 30 | 300.0000 |
| 42 | 420.0000 |
| 60 | 600.0000 |
How to use this table
Find the row closest to your number of sides and read across to the perimeter. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Regular Polygon Perimeter Calculator for a precise answer.
Need a value that is not in the table? — the Regular Polygon Perimeter Calculator does it instantly, for free, with the formula and a worked example built in.
