Perimeter and Area: Calculating Perimeter

The video tutorial introduces units of distance and length, such as miles, kilometers, feet, meters, inches, and centimeters. It explains how to calculate the perimeter of polygons, focusing on rectangles and squares. The perimeter of a rectangle is calculated by adding the lengths and widths, while the perimeter of a square is found by multiplying the length of one side by four. Examples include measuring a room and a piece of paper to find their perimeters.
