Description

This example demonstrates how to calculate the perimeter of a square. The square ABCD has sides measuring 6 units each. To find the perimeter, we use the formula P = 4s, where s is the length of a side. In this case, P = 4 × 6 = 24 units.

Understanding perimeter is a fundamental concept in geometry that has numerous real-world applications. This collection of examples helps students visualize and compute perimeters of various quadrilaterals, starting with simple shapes like squares and progressing to more complex ones. By exploring different dimensions and shapes, students develop a robust understanding of how perimeter relates to the dimensions of a shape.

Exposure to multiple worked-out examples is crucial for students to fully grasp the concept of perimeter. Each example reinforces the basic principle while introducing slight variations, allowing students to recognize patterns and develop problem-solving strategies. This approach helps build confidence and proficiency in applying formulas and reasoning through geometric problems.

Teacher Script: "Let's look at this square. Can you see how all sides are equal? That's what makes it a square. Now, we know each side is 6 units long. To find the perimeter, we need to add up all four sides. But since all sides are equal, we can simply multiply the side length by 4. So, 4 × 6 = 24. The perimeter of our square is 24 units. Remember, we always include the units when giving our answer! Can you think of any real-life objects that might have a square shape?"
