Area and Perimeter of Rectangles

Mr. Hul presents a lesson on calculating the area and perimeter of rectangles, using examples to demonstrate the formulas. The lesson includes finding the width of a rectangle given its area and length, and a practical example of measuring a desk. The video concludes with a challenge to apply these concepts to classroom objects.

What is the first step in finding the area of a rectangle?
