The perimeter of a polygon is the measurement of the total length of all its sides

The perimeter of a polygon is the measurement of the total length of all its sides. It is typically expressed in units such as centimeters, meters, inches, or feet. The formula to find the perimeter of a polygon may differ depending on the shape of the polygon.

Here are a few common formulas for finding the perimeter of different polygons:

1. Perimeter of a rectangle or square: To find the perimeter of a rectangle or square, add up the lengths of all four sides. The formula is P = 2l + 2w, where P represents the perimeter, l denotes the length, and w indicates the width.

2. Perimeter of a triangle: To find the perimeter of a triangle, add the lengths of all three sides. The formula is P = side1 + side2 + side3, where P represents the perimeter.

3. Perimeter of a circle: The perimeter of a circle is also known as its circumference. It can be calculated using the formula C = 2πr, where C represents the circumference and r denotes the radius of the circle. Alternatively, the formula C = πd can be used, where d represents the diameter of the circle.

4. Perimeter of a regular polygon: A regular polygon is a polygon where all sides and angles are equal. To find the perimeter of a regular polygon, multiply the length of one side by the number of sides. The formula is P = n * s, where P represents the perimeter, n denotes the number of sides, and s indicates the length of each side.

It is important to note that the units used for perimeter should be consistent with the units used to measure the sides. Make sure to double-check the measurements and units to ensure accurate calculations.
