The video tutorial explains how to find the width and length of a rectangle given that its length is 3 inches more than its width and its area is 130 square inches. The process involves setting up a quadratic equation using the area formula, solving it by factoring, and validating the solution to ensure positive dimensions. The final solution reveals the width as 10 inches and the length as 13 inches, confirming the area and the condition that the length is 3 inches more than the width.
