Exploring Area Problems with Rectangles

This video tutorial covers lesson 11.7 on solving word problems related to the area of rectangles. It emphasizes the importance of understanding previous lessons and introduces a strategy to solve area problems by identifying patterns. The tutorial provides examples of calculating area using multiplication and division, explores patterns when dimensions are doubled or halved, and guides students in recognizing patterns and completing tables. The lesson concludes with a preview of the next topic, the area of combined rectangles.

What is the first step in solving area problems?

• Check if the answer makes sense

• Read and understand the problem

• Choose a strategy

• Identify important information

What operation is used to calculate the area of a rectangle?

How can you find a missing side length if you know the area of a rectangle?

• Divide the area by the known side length

• Add the area and the known side length

• Subtract the known side length from the area

• Multiply the area by the known side length

What happens to the area of a rectangle if you double the width but keep the length the same?

• The area remains the same
