Finding the Perimeter of Rectangles Using Area Models

This video tutorial teaches how to find the perimeter of a rectangle using area models. It begins with an introduction to rectangles and their properties, explaining that a rectangle is a quadrilateral with four right angles and congruent opposite sides. The tutorial then demonstrates how to calculate the perimeter by placing unit squares around the rectangle's edges, emphasizing the difference between area and perimeter. An example of a rectangular walking track is used to illustrate the process, concluding with a summary of the key concepts learned.

Explain the difference between area and perimeter.

How many line segments are there around the perimeter of the rectangular walking track?
