Exploring Perimeter Calculations for Rectangles

Mr. Ahmed introduces the concept of perimeter, focusing on rectangles and squares. He explains how to calculate perimeter using both addition and multiplication, providing examples with a garden and various shapes. The lesson covers formulas for perimeter, including the use of the distributive property to simplify calculations. Students are encouraged to practice these concepts through examples and are provided with a summary of the key points.
