Understanding Area

This video tutorial introduces the concept of area as a two-dimensional measure of space within a shape's boundaries. It explains how to measure area by comparing an object to a known unit of area, such as square inches, square feet, or square centimeters. The tutorial provides examples of calculating area for different shapes using these units, demonstrating the process of counting unit squares to determine total area. Formulas for calculating the area of geometric shapes are also briefly mentioned.
