Area Calculation and Rectangle Properties

This video tutorial explains how to calculate the area of a rectangle using a grid. It begins by identifying the shape and the formula for area calculation, which is base times height. The tutorial then defines the base and height of a rectangle and demonstrates how to use a grid to measure these dimensions. Finally, it shows how to calculate the area by multiplying the base and height and emphasizes the importance of using the correct units. The video concludes with instructions for solving similar exercises.
