Calculating Area of Rectangles

This video tutorial explains how to calculate the area of rectangles, starting with whole number side lengths and progressing to fractional side lengths. It introduces the concept of using unit squares to measure area and demonstrates the formula for calculating the area of a rectangle. The tutorial then explores how to handle fractional side lengths by dividing unit squares into parts and using area models to visualize and calculate the area. The lesson concludes with a verification of the calculations and a summary of the key concepts covered.
