Finding Perimeter: Solving Real-World Problems

This lesson teaches how to find the perimeter of polygons through real-world problems. It begins with a review of perimeter and area concepts, emphasizing the difference between them. The lesson includes two practical examples: calculating the perimeter of a rectangular soccer field and determining the fencing needed for a square garden. By visualizing and solving these problems, students learn to apply perimeter calculations in real-life scenarios.
