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 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.

25 maj 2023 · In simple words, the area is the whole amount of space inside an object. For example, for the rectangle shown in the following image, the darker region inside the square shape is its area. On the other hand, the perimeter is the measured distance around a shape.
The perimeter of a triangle is the sum of all three sides. In the case of an equilateral triangle, since all three sides are equal in length, the perimeter can be calculated as 3 × side-length. The formula of perimeter of triangle = (a + b + c) units, where a, b, and c are the sides of the triangle. Where do we Use Perimeter in Real Life?
