Geometry

Description

This example demonstrates how to calculate the area of a rectangle. The rectangle ABCD has a length of 12 units and a width of 8 units. To find the area, we use the formula A = l × w, where l is the length and w is the width. In this case, A = 12 × 8 = 96 square units.

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

Exposure to multiple worked-out examples is crucial for students to fully grasp the concept of area. 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 examine this rectangle. Notice how it has two different side lengths - we call the longer side the length and the shorter side the width. To find the area, we multiply these together. So, 12 units times 8 units gives us 96 square units. Always remember to include the units in your answer! Can you think of any real-life objects that might have these dimensions?"
