Title: Perimeter: A Comprehensive Guide
Subtitle: Learn How to Calculate the Perimeter of Different Shapes
Method:
Perimeter is the total length of the outside of a shape. It is calculated by adding up the lengths of all the sides of the shape. To calculate the perimeter of a shape, you must first identify the type of shape and then use the appropriate formula to calculate the perimeter.
Examples:
To calculate the perimeter of a square, you would use the formula P = 4s, where s is the length of one side of the square. To calculate the perimeter of a rectangle, you would use the formula P = 2l + 2w, where l is the length and w is the width of the rectangle. To calculate the perimeter of a triangle, you would use the formula P = a + b + c, where a, b, and c are the lengths of the sides of the triangle.
