1. • Distance around a two dimensional shape

     • Perimeter is the distance around a two dimensional shape, a measurement of the distance around something; the length of the boundary. A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference.

   What is the perimeter of a two dimensional figure?

   • 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.\\)

   What is the perimeter of a circle?

   • For example, the perimeter (or circumference) of a circle is \\ (2\\pi r,\\) where \\ (r\\) is the radius of the circle. Fascinatingly, some shapes (such as certain fractals) have infinite perimeter, despite having a finite area. What is the perimeter of a square with side length 6?
