Perimeter of Plane Figures

The video tutorial explains the concept of perimeter using an ant's journey around a rectangle. The ant starts at the top left corner, moves along the sides of the rectangle, and returns to the starting point, covering a total distance equal to the perimeter. The tutorial further explains that the perimeter is the total length around any plane figure, not just rectangles, using examples of other shapes like rhombuses.
