- Perimeter[ <Polygon> ]
- Returns the perimeter of the polygon.
**Example:**`Perimeter[Polygon[(1, 2), (3, 2), (4, 3)]]`

yields*6.58*.

- Perimeter[ <Conic> ]
- If the given conic is a circle or ellipse, this command returns its perimeter. Otherwise the result is undefined.
**Example:**`Perimeter[x^2 + 2y^2 = 1]`

yields*5.4*.

- Perimeter[ <Locus> ]
- If the given locus is finite, this command returns its approximate perimeter. Otherwise the result is undefined.
