The video tutorial explains the concept of perimeter using a garden fence analogy. It demonstrates how to calculate the perimeter of rectangles by counting steps around them and introduces the formula for perimeter as 2 times the length plus 2 times the width. The tutorial uses variables to simplify the formula and provides examples of applying the formula to find the perimeter of given rectangles.
