Decomposing Rectangles

This video tutorial teaches how to decompose rectangles using benchmark numbers. It begins with an introduction to benchmark numbers and their role in making estimates. The tutorial then demonstrates decomposing various arrays and rectangles, such as 3x9, 4x8, 12x4, and 4x7, using benchmark numbers like 5 and 10. Each decomposition is shown step-by-step, illustrating how the original area is divided into smaller parts while maintaining the same total area. The lesson concludes by summarizing the decomposition process using benchmark numbers.
