Calculating Perimeter and Area of Shapes

This video tutorial covers the concepts of finding the area and perimeter of rectangles, squares, and triangles. It begins with definitions of these shapes and explains how to calculate their perimeters by summing the lengths of their sides. The video then moves on to calculating the area, demonstrating the formulas for each shape: length times width for rectangles, side squared for squares, and base times height divided by two for triangles. The tutorial concludes with examples to reinforce these concepts.
