The perimeter is a measurement of the total distance around the outside of a two-dimensional shape

The perimeter is a measurement of the total distance around the outside of a two-dimensional shape. It is the sum of all the sides or lengths of the shape.

To calculate the perimeter of a shape, you need to add up the lengths of all its sides. The unit of measurement used for the perimeter will depend on the given dimensions of the shape.

For example, if you have a rectangle with length (l) and width (w), the perimeter (P) can be calculated using the formula: P = 2(l + w).

For a square, where all sides are equal, the perimeter (P) can be calculated using the formula: P = 4s, where “s” represents the length of one side.

In the case of a circle, you can find the perimeter, which is also called the circumference (C), using the formula: C = 2πr, where “r” is the radius of the circle and π is a mathematical constant approximately equal to 3.14.

Perimeter is an important concept in mathematics as it helps us understand and measure the boundaries of shapes. It is used in various real-life situations, such as calculating fencing requirements for a garden, determining the amount of border required for a picture frame, or estimating the length of a wire needed to enclose an area.
