To determine the scale factor Kamla uses to create the parallelogram on the right, we need to compare the corresponding side lengths of both parallelograms.
The corresponding side lengths are:
Left parallelogram: 1 in., 3.5 in., 5 in., 0.7 in.
Right parallelogram: ?
By comparing the side lengths, we can find the scale factor as follows:
1 in. / ? = 3.5 in. / 1 in.
1 in. / ? = 5 in. / 3.5 in.
1 in. / ? = 0.7 in. / 5 in.
Now we can solve each equation to find the scale factor.
1. 1 in. / ? = 3.5 in. / 1 in.
? * 1 in. = 1 in. * 3.5 in.
? = 3.5 in. / 1 in.
? = 3.5
2. 1 in. / ? = 5 in. / 3.5 in.
? * 1 in. = 3.5 in. * 5 in.
? = (3.5 in. * 5 in.) / 1 in.
? = 17.5
3. 1 in. / ? = 0.7 in. / 5 in.
? * 1 in. = 5 in. * 0.7 in.
? = (5 in. * 0.7 in.) / 1 in.
? = 3.5
By comparing the three scale factors obtained, we can see that Kamla used a scale factor of 3.5 to create the parallelogram on the right.
To determine the scale factor Kamla used, we need to compare the corresponding measurements of the sides of the two parallelograms.
Let's list the corresponding side lengths of the parallelograms:
Left parallelogram:
Side 1: 1 in.
Side 2: 3.5 in.
Right parallelogram:
Side 1: 5 in.
Side 2: 0.7 in.
To find the scale factor, we can divide the corresponding side lengths of the right parallelogram by the corresponding side lengths of the left parallelogram:
Scale factor for side 1: 5 in. / 1 in. = 5
Scale factor for side 2: 0.7 in. / 3.5 in. = 0.2
Since scale factors are usually expressed as decimals or fractions, we can round the scale factor for side 2 to 0.2.
Therefore, Kamla used a scale factor of 5 for side 1 and a scale factor of 0.2 (or 1/5) for side 2.
The correct scale factor to choose from the options provided is 04 (which seems like a typo and should probably be 0.4).

A. 5
B. 0.2
C. 4
D. 3.5
To determine the scale factor, we can compare the corresponding sides of the parallelograms on the left and right.
The corresponding sides are:
- Top side: 1 in. to 3.5 in.
- Right side: 3.5 in. to 5 in.
- Bottom side: 5 in. to 0.7 in.
- Left side: 0.7 in. to unknown
To find the scale factor, we divide the corresponding side lengths of the right parallelogram by the corresponding side lengths of the left parallelogram.
For the top side: 3.5 in. / 1 in. = 3.5
For the right side: 5 in. / 3.5 in. ≈ 1.43
For the bottom side: 0.7 in. / 5 in. = 0.14
For the left side: 0.7 in. / 1 in. = 0.7
Since the scale factor should be the same for all sides, we take the average of the scale factors calculated above:
(3.5 + 1.43 + 0.14 + 0.7) / 4 ≈ 1.4425
Therefore, the scale factor used by Kamla is approximately 1.4425, which is not listed as one of the provided answer choices. Please double-check the options or provide additional information.
