This animation shows two similar rectangles with side lengths in a 2:3 ratio, visually growing the smaller shape into the larger one. It highlights that area scales by the square of the side ratio, not the ratio itself, by overlaying a grid that multiplies in both directions. Given the smaller rectangle's area of 20 square units, the animation walks through finding the larger rectangle's area of 45 square units. Useful for students learning about similarity, scale factors, and area relationships in geometry.
