Understanding Rectangles and Perimeter

The video tutorial explains how to determine the perimeter of a rectangle using models. It begins with an introduction to the formula for perimeter, followed by a detailed example calculation. The tutorial then presents a word problem involving a classroom space, demonstrating the practical application of the perimeter formula. The key takeaway is understanding that the perimeter of a rectangle is the sum of all its sides, and this concept is reinforced through examples and a real-world problem.
