Calculating Area of Shapes

The video tutorial introduces the concept of area, explaining it as the measure of a surface in square units. It covers two methods to find the area: counting unit squares and using formulas. The tutorial provides examples for calculating the area of rectangles and squares using these methods. It emphasizes the importance of remembering formulas for easy calculation.
