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. The perimeter of a circle is called the circumference: Circumference = 2 π × radius. Perimeter = very hard!

What is a Perimeter? 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 …

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.

The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions. For example, imagine a triangle made of a wire of length L.

Perimeter is a simple yet essential concept in geometry that helps us measure the boundaries of various shapes. Whether it's a rectangle, square, triangle, or even a circle, knowing how to calculate the perimeter is a valuable skill that applies to many practical situations.

Area and perimeter are two commonly discussed measurements of 2D figures (plane figures). The area of a figure is a measurement of the amount of space the figure takes up. Another way to think of area is as the measure of the space enclosed by a figure. For example, the area of a square is made up of the space between each side of the square.

Common geometric shapes include triangles, quadrilaterals and circles, and many everyday objects have faces that are made up of these shapes. The perimeter of a shape refers to the length of its boundary. For a circle this is also referred to as its circumference.

The perimeter is the total length or distance around a two dimensional shape. In the figure below, the perimeter of each shape is the sum of the lengths of each side, shown in red.
