Question 1
Points: 1
Jenna is creating a mural for her bedroom wall. She would like to copy a picture that is 2 in. by 2.5 in. She uses a copy machine to enlarge it by a scale factor of 4. Then she projects it on her wall by a scale factor of 12. What are the dimensions of the mural? Are the enlarged pictures similar to the original?
Explanation
The total scale factor is the product of the individual scale factors: 4 × 12 = 48. Multiplying the original dimensions by this factor: 2 × 48 = 96 and 2.5 × 48 = 120. Dilations preserve similarity.
