Lesson 1. Practice Problem #2. Rectangle A has length 12 and width 8. Rectangle B has length 15 and width 10. Rectangle C has length 30 and width 15. Using the information above, answer the following - A) If Rectangle A is a scaled copy of Rectangle B, what is the scale factor? B) If Rectangle B is a scaled copy of Rectangle A, what is the scale factor? C) Rectangle C is not a scaled copy of Rectangle B. This is because, although the length of Rectangle C is that of Rectangle B, this is not true of the width.
