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.
Kamla draws the parallelogram on the left and then uses a scale factor to create the parallelogram on the right. All measurements are in inches. What scale factor does he use?
A. 4
B. 0.2
C. 5
D. 3.5

Answer 1

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 ÷ 3.5 is approximately 0.2.
