The video tutorial introduces the concepts of perimeter, area, and volume, essential components of mathematics. It begins with an overview of the chapter's importance, followed by detailed explanations of perimeter, including definitions and formulas for different shapes like squares and rectangles. The tutorial then explores the concept of area, explaining how to calculate it for various shapes. Finally, it introduces volume, describing it as the space enclosed by three-dimensional objects, and provides formulas for calculating the volume of cuboids and cubes. The video emphasizes understanding these basics before proceeding to exercises.
