Definition

The perimeter of a geometric figure is the distance around the edge of the figure. Perimeter is often denoted by P. The perimeter of a circle is called its circumference.

Formulas

  • Square - 4s, where s is the side length
  • Rectangle - 2(l+w), where l is the length and w is the width
  • Circle - $2\pi r$, where r is the radius
  • Regular geometric figure with n sides - ns, where s is the length of the side
