Area of Rectangles Concepts

The video tutorial teaches how to find the area of rectangles. It begins with an introduction to using unit squares to measure area and then explains a more efficient method by multiplying the side lengths of rectangles. The tutorial includes guided practice problems and encourages independent practice to reinforce the concept.
