The video tutorial explains how to calculate the area of a rectangle that contains three identical circles, each with a radius of 24 millimeters. The instructor guides through identifying the rectangle's dimensions by using the properties of an equilateral triangle formed by the circle centers. Trigonometry is used to find the height of the triangle, which helps determine the rectangle's width. The area is then calculated and rounded to three significant figures. The instructor reflects on the problem-solving process and suggests alternative methods, emphasizing the importance of practice and experience in solving unique geometry problems.
