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?

Question

left parallelogram: 5 inches bottom 3.5 inches sides

right parallelogram: 0.7 inches bottom 1 inches top.

A. 0.2
B. 5
C. 3.5
D. 4

Answer 1

To find the scale factor, we can compare the corresponding sides of the two parallelograms.

The bottom side of the left parallelogram is 5 inches, and the corresponding bottom side of the right parallelogram is 0.7 inches.

The scale factor is found by dividing the length of the right parallelogram's bottom side by the length of the left parallelogram's bottom side:

0.7 inches / 5 inches ≈ 0.14

Therefore, the scale factor is approximately 0.14.

None of the provided answer choices match the calculated scale factor of 0.14.
