The figure is not attached. So we will assume a rectangle that has sides of lengths 2 cm and width 3 cm and It is enlarged with scale factor 3.
The width of the original rectangle must be one-third of the enlarged rectangle.
The lengths of the sides of the enlarged rectangle will be:
3 × 2 cm = 6 cm (Length)
3 × 3 cm = 9 cm (Width)
