Introduction to Perimeter

The video tutorial explains how to calculate the perimeter of various figures, including a garden, park, pool, and different geometric shapes. It uses the journey of an ant to illustrate the concept of perimeter, showing how to add the lengths of all sides to find the total distance around a figure. The tutorial also covers measuring perimeters using a string and compares the boundaries of different shapes, including circles.
