Calculating Perimeters of Shapes

The video tutorial by Mr. Weekend explains how to calculate the perimeter of various two-dimensional shapes, including squares, rectangles, parallelograms, trapezoids, and triangles. It covers the basic concept of perimeter as the distance around a figure and demonstrates different methods to calculate it, such as using formulas or simply adding the lengths of all sides. The tutorial emphasizes not including internal heights in perimeter calculations.
