Perimeter Formula of a Rectangle

The video tutorial explains the formula for calculating the perimeter of a rectangle, which is p = 2l + 2w, where p is the perimeter, l is the length, and w is the width. It provides an example using Luca's garden, which is 8 feet long and 4 feet wide. By substituting these values into the formula, the perimeter is calculated as 24 feet. The tutorial emphasizes the importance of using the order of operations in calculations and concludes by summarizing the lesson on finding the perimeter of a rectangle.
