Calculating Area of Rectangles

The video tutorial explains how to find the area of a rectangle using a formula. It introduces key vocabulary such as area, base, and height, and explains how to identify these in a rectangle. The concept of unit squares is introduced to help visualize area calculation. The formula for area, which is base times height, is demonstrated with several examples. The tutorial also provides practice problems for viewers to apply what they've learned.
