Calculating Perimeters and Areas

This video tutorial covers the concepts of perimeter and area for various geometric shapes, including squares, rectangles, triangles, parallelograms, and trapezoids. It explains how to calculate the perimeter by summing the side lengths and how to find the area using specific formulas for each shape. The tutorial also includes application problems to demonstrate the practical use of these calculations in real-world scenarios.
