Perimeters

Let us learn what is perimeter,

The term perimeter refers either to the curve constituting the boundary of a lamina, or else to the length of this boundary.

The perimeter of a circle is called the circumference.

The perimeters of some common laminas are summarized in the table below. In the table, e is the eccentricity of an ellipse, a is its semimajor axis, and E(k) is a complete elliptic integral of the second kind.
I hope the above explanation was useful.
