The total distance around a two-dimensional shape.

Description

The perimeter is the total length of the sides or edges of a two-dimensional shape. This concept is fundamental in geometry and is used to measure the boundary length of various shapes. For example, the perimeter of a rectangle is calculated using the formula 

P = 2(l + w)

where l l is the length and w w is the width. Understanding perimeter is crucial for solving problems related to measurements and dimensions in geometry.
