Answer :
Answer:
The scale factor is 1.5
Step-by-step explanation:
In the picture attached, the line AB is shown.
The first 3 steps are to measure some lengths
- OA = 2 units OA’ = 3 units
- OB = 3 units OB’ = 4.5 units
- AB = 2.2 A’B’= 3.3
The last 3 steps are to compute these ratios
- OA'/OA = 3/2 = 1.5
- OB'/OB = 4.5/3 = 1.5
- A'B'/AB = 3.3/2.2 = 1.5

Answer:
see explanation
Step-by-step explanation:
1. Measure these lengths:
OA - 2.0 units
OA' - 3.0 units
2. Measure these lengths:
OB - 3.0
OB' - 4.5
3. Measure these length's:
AB - 2.2
AB' - 3.3
4. Calculate the ration: OA' / OA = 1.5
5. Calculate this ratio: OB' / OB = 1.5
6. Calculate this ratio: A'B' / AB = 1.5
