Lesson 01: Projecting and Scaling | Unit 2: Dilations, Similarity, and Introducing Slope

Rectangle A measures 12 cm by 3 cm. Rectangle B is a scaled copy of Rectangle A. Select **all** of the measurement pairs that could be the dimensions of Rectangle B.

Rectangle A has length 12 units and width 8 units. Rectangle B has length 15 units and width 10 units. Rectangle C has length 30 units and width 15 units. Is Rectangle A a scaled copy of Rectangle B? If so, what is the scale factor?

Rectangle B has length 15 units and width 10 units. Is Rectangle B a scaled copy of Rectangle A with length 12 units and width 8 units? If so, what is the scale factor?
