Perimeter is a mathematical term that refers to the total length of the boundary of a two-dimensional (2D) shape

Perimeter is a mathematical term that refers to the total length of the boundary of a two-dimensional (2D) shape. It is the distance around the outside of the shape.

To calculate the perimeter of a shape, you add up the lengths of all its sides. The units of measurement for perimeter are the same as the units of measurement for the lengths of the sides.

For example, let’s consider a rectangle. A rectangle has four sides, two pairs of equal lengths. To find its perimeter, you add up the lengths of all its sides, which are typically denoted as l (length) and w (width). The formula for finding the perimeter of a rectangle is P = 2(l + w), where P represents the perimeter.

In the case of a square, all four sides have the same length, denoted as s. The formula to find the perimeter of a square is P = 4s.

Other shapes, such as triangles and circles, may have different formulas to calculate their perimeters. It is important to understand the properties of each shape to determine the appropriate formula.

Perimeter is an essential concept in geometry and is used to analyze and find the total distance around various shapes. It helps us understand the size and dimensions of different objects, such as rooms, fences, and even entire cities.
