Finding Dimensions and Area of Rectangles

The video tutorial demonstrates how to use the area of a rectangle to find a missing dimension, specifically the length, when the width is known. The instructor sets up the problem by stating the area and width, then uses division to solve for the missing length. The process involves converting numbers into fractions and applying an algorithm to find the solution. The tutorial concludes with a verification step to ensure the solution is correct, reinforcing the concept of using area and one known dimension to find the other.
