Calculating Area and Perimeter

This video tutorial covers the concepts of perimeter and area, focusing on rectangular shapes. It explains how to calculate the perimeter by adding the lengths of the sides and how to find the area by multiplying the lengths of the sides. The tutorial also addresses more complex shapes by dividing them into simpler rectangles to calculate their perimeter and area. The video concludes with examples to reinforce the concepts.
