cube 1: Cube 2:
5 in. 0.7 in.
3.5 in. 1in.
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?
Options:
3.5
0.2
5
4
To find the scale factor, we divide the corresponding sides of the parallelograms.
For the side lengths of the parallelogram:
5 in. / 0.7 in. = 7.14
For the side lengths of the parallelogram:
3.5 in. / 1 in. = 3.5
Since the scale factor is the same for all corresponding sides, we can take the average of the two ratios above:
(7.14 + 3.5) / 2 ≈ 5.32 / 2 ≈ 2.66
So, the scale factor Kamla uses is approximately 2.66.
