The video tutorial introduces students to the concepts of area and perimeter, explaining how to calculate each for rectangles and squares. It begins with an overview of area, demonstrating how to count square units and derive a formula using length and width. The lesson then transitions to perimeter, showing how to measure the distance around a figure and create a formula for rectangles. The tutorial also covers the special case of squares, where all sides are equal, and provides two methods for finding perimeter. Finally, students are guided through practice activities to reinforce their understanding.
