Finding the Area of a Rectangle with Fractional Sides by Tiling

This video tutorial teaches how to find the area of a rectangle with fractional side lengths using tiling. It begins with an introduction to the concept of fractional sides and provides an example of a yard that is 3/4 mile wide by 2/5 mile long. The lesson reviews the basic method of finding the area of a rectangle by multiplying length and width. It then explains how multiplying fractions involves finding a part of a part, using models to visualize the process. By overlapping these models, the video demonstrates how to calculate the area of a rectangle with fractional sides, resulting in an area of 6/20 square miles. The lesson concludes by summarizing the method of using tiling to find the area with fractional sides.
