In geometry, the perimeter of a shape is defined as the total length of its boundary. The perimeter of a shape is determined by adding the length of all the sides and edges enclosing the shape. It is measured in linear units of measurement like centimeters, meters, inches, or feet.
Perimeter is the distance around a two-dimensional shape. Example: the perimeter of this rectangle is 7+3+7+3 = 20. Example: the perimeter of this regular pentagon is: 3 + 3 + 3 + 3 + 3 = 5×3 = 15. The perimeter of a circle is called the circumference: Circumference = 2 π × radius.

Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.
The perimeter of a two-dimensional figure is the length of the boundary of the figure. If the figure is a polygon such as a triangle, square, rectangle, pentagon, etc., then the perimeter is the sum of the edge lengths of the polygon. For example, a square with side length 3 has perimeter \ (3+3+3+3 = 12.\)
