Let parallelogram Right parallelogram

Side width: 3.5 in Side width: 1 in
Length: 5 in Length 0.7

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. 0.2

B. 4

C. 5

D. 3.5

1 answer

To find the scale factor, we need to divide the corresponding side lengths of the two parallelograms.

For the side widths, we have:
Scale factor = Width of right parallelogram / Width of left parallelogram
Scale factor = 1 in / 3.5 in
Scale factor ≈ 0.286 (rounded to 3 decimal places)

For the lengths, we have:
Scale factor = Length of right parallelogram / Length of left parallelogram
Scale factor = 0.7 in / 5 in
Scale factor = 0.14

Since the scale factor for the side widths and the scale factor for the lengths are not the same, we cannot determine a single scale factor for the entire parallelogram. Therefore, none of the given options are correct.
