This video tutorial teaches how to find the area of a rectangle by decomposing it into smaller rectangles. It begins with a review of basic area calculation using multiplication and introduces the concept of decomposing numbers into simpler parts using number bonds. The tutorial provides examples of decomposing both columns and rows to simplify multiplication, making it easier to calculate the area of rectangles with larger side measurements. The video emphasizes that there are multiple ways to decompose numbers and encourages choosing the method that makes the most sense for the problem at hand.
