Let parallelogram Right parallelogram

Question

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

Answer 1

To determine the scale factor, we can divide the corresponding side lengths of the two parallelograms.

For the side width, the scale factor is 3.5/1 = 3.5.

For the length, the scale factor is 5/0.7 = 7.14 (rounded to two decimal places).

Since the scale factor should be the same for both the width and the length, we can conclude that Kamla used a scale factor of 3.5.

Therefore, the answer is D. 3.5.
