Understanding Perimeter and Area

Miss Hanahan introduces the concepts of perimeter and area, explaining how to calculate each using simple formulas. The lesson focuses on understanding that shapes can have the same perimeter but different areas. Through examples and practice problems, students learn to apply these concepts to rectangles and squares, reinforcing the idea that the perimeter is the sum of all sides, while the area is the product of length and width. The video concludes with a summary and encourages students to ask questions or solve problems based on the lesson.
