Finding the Area of a Rectangle: Applying the Formula

This video tutorial teaches how to find the area of a rectangle using a formula. It begins with an introduction to rectangles, explaining their properties and dimensions. The commutative property of multiplication is discussed, followed by a demonstration of calculating area by counting squares and using the formula length times width. The importance of labeling area in square units is emphasized. Finally, a practical example of calculating the flooring needed for a dog pen is provided, reinforcing the application of the area formula.
