Dilate the rectangle below by a scale factor of 2. If the current side lengths are 15

and 8, what are the side lengths on the new dilated rectangle?
In your answer, give the new side lengths for the dilated image and explain how you
calculated them.

8 cm
C
D

Answer 1

AB and CD would be 30

AC and BD would be 16

The scale factor is what you multiply the sides by. Dilate means wider or larger so you multiply each side by the scale factor of 2 to get the higher scaled rectangle.
