Question

What is the scale factor used to make the new rectangle smaller? The corresponding sides are 9 and 3, and the bottom is 15 and 5.

A. 2
B. 1/2
C. 3
D. 1/3

Answer 1

The scale factor used to make the new rectangle smaller is 1/3.

Step-by-step explanation:

The scale factor used to make the new rectangle smaller can be determined by taking the ratio of the corresponding sides. In this case, the corresponding sides are 9 and 3, and the bottom sides are 15 and 5. To find the scale factor, divide the length of the corresponding sides of the smaller rectangle by the length of the corresponding sides of the larger rectangle. So, the scale factor is 3/9 or 1/3, which corresponds to option D.
