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.
