Front

If a rectangle has a length of 4 cm and a width of 2 cm, what are the dimensions of the rectangle after applying a scale factor of 3?

Back

The new dimensions will be 12 cm (length) and 6 cm (width).

Front

What is the relationship between the areas of two similar figures when the scale factor is k?

Back

The area of the larger figure is k² times the area of the smaller figure.

Front

If the scale factor is 1, what does this indicate about the two figures?

Back

The two figures are congruent.
