Finding Area of Rectangles

This video tutorial teaches how to find the area of a rectangle or square by counting square units. It explains the concept of area as the space within a closed shape and distinguishes it from perimeter, which is the distance around the shape. The tutorial demonstrates how to lay square tiles side by side without gaps or overlaps to cover the area of a shape. It also covers measuring area in square units and provides a step-by-step guide to counting square tiles to determine the area of a rectangle. The lesson concludes with a summary of the key points covered.
