Properties and Calculations of Squares and Rectangles

This video lesson by Mr. Saad covers the concepts of perimeter and area for grade 4 students. It explains how to calculate the perimeter by adding the lengths of all sides of a closed figure and introduces the concept of area as the number of square units inside a figure. The lesson includes examples with rectangles and squares, demonstrating the formulas for both perimeter and area. Students are encouraged to solve exercises and verify their answers using the video.
