Perimeter is the sum of the sides of a polygon. It is a distance and therefore is a one-dimensional property. The perimeter of a circle is called its circumference, and can be found using the formula Circumference = 2(pi)(radius). For a square, the perimeter = 4(side length), and for a rectangle, perimeter = 2(length of the width) + 2(length of the height).
