The video tutorial covers the concept of scaled rectangles through an activity involving three rectangles: R, B, and C. It explains how B is a scaled copy of R with a scale factor of 1/2, and C is a scaled copy of B with a scale factor of 1/3. Consequently, C is also a scaled copy of R with a scale factor of 1/6. The tutorial further explores the area relationships between these rectangles, showing that the area of B is 1/4 of R, and the area of C is 1/36 of R. The video concludes by discussing the alignment of diagonals in scaled rectangles.
