# What Is a Perimeter Example?

A perimeter example is a figure/shape with the total distance covered around its edge. It is very similar to the area of a shape and can be found easily by multiplying the length of its edge with 2.

There are many shapes with varying areas and their perimeters. They include squares, triangles, circles and irregular polygons, among others. These figures/shapes have a number of practical applications, such as the amount of string needed to wrap around a spool and the total length of a fence that surrounds a yard.

#### What is the difference between the area and the perimeter of a rectangle?

A rectangular shape has two pairs of equal sides and the perimeter can be calculated by adding these sides together. Similarly, a parallelogram has two pairs of equal sides and the perimeter is the same as the sum of these two sides.

What is the perimeter of a rectangle with length 12 cm and breadth 5 cm?

The perimeter of a rectangle with length 12 cm is the total distance covered around its edge. This is the same as the length and width of the rectangle, i.e., the perimeter is 2 (L + W).

What is the perimeter of a triangle with base length 19 cm and height 12cm?

The triangle has three sides and the perimeter is the total distance covered by these three sides. This can be done easily by finding the perimeter of the triangle with its base length and calculating the lengths of the other sides.

What is the perimeter of an equilateral triangle with side lengths 20 cm, 15 cm and 18 cm?

The equilateral triangle has three sides and its perimeter is the total distance covered by all of these sides. This can be done easily by finding out the perimeter of the triangle with its base length, a and b and then calculating the lengths of the other sides.

#### How can you calculate the perimeter of a circle?

A circle is a figure with the same number of angles as its base and the radius. If we know the circumference of a circle, we can calculate its perimeter with very little effort.

#### How can you calculate the perimeter in mm?

A circle’s perimeter can be calculated using the following equation: where r displaystyle r is the radius of the circle, d displaystyle d is the diameter of the circle, and p displaystyle p is the number of vertices.

#### What is the perimeter of equilateral triangle with base length 12cm?

The perimeter of an equilateral triangle with base length 12cm is 21cm. The perimeter of an equilateral triangle can also be determined by using the formula that has two digits, a and b, for its sides.

#### How can you find the perimeter of an irregular polygon?

Regular polygons have the same formula for their perimeter as a regular triangle, which is: where a, b, and c are the lengths of the sides. However, the formula for a irregular polygon is different from that of a regular polygon.
