Perimeter is the distance around a two dimensional shape, or the measurement of the distance around something;the length of the boundary. A perimeter is a path that surrounds an area. The word comes from the Greek peri (around) and meter (measure). The term may be used either for the path or its length - it can be thought of as the length of the outline of a shape. The perimeter of a circular area is called circumference.

Practical uses

The formula for the perimeter of a rectangle. When a circle's radius is 1, its perimeter is 2?, which is also the distance it rolls in one revolution. Calculating the perimeter has considerable practical applications. The perimeter can be used to calculate the length of fence required to surround a yard or garden. The perimeter of a wheel (its circumference) describes how far it will roll in one revolution. Similarly, the amount of string wound around a spool is related to the spool's perimeter.
