B. 0.2
To find the scale factor, you divide the corresponding side lengths of the two shapes.
For the first shape: 5 in / 0.7 in = 7.14
For the second shape: 3.5 in / 1 in = 3.5
We can see that the scale factor is approximately 0.2, as 7.14 รท 3.5 is approximately 0.2.
Use the image to answer the question.
there's two shapes for the first shape the measurements are 5 in, and 3.5 in, for the second shape the measurements are 0.7 in, and 1 in.
