Question

multiple choice 10 points the rectangle on the right is a scaled copy of the rectangle on the left. identify the scale factor. 33 15 11 5 2 3 1/3 1/2

Explanation:

Step1: Recall scale - factor formula

The scale factor from the original rectangle to the scaled - copy is found by dividing the corresponding side lengths of the scaled - copy by the original rectangle. Let's use the length of the rectangles.

Step2: Calculate scale factor

The length of the original rectangle is 33 and the length of the scaled - copy is 11. The scale factor $k=\frac{\text{length of scaled - copy}}{\text{length of original}}=\frac{11}{33}=\frac{1}{3}$. We can also check with the width. The width of the original rectangle is 15 and the width of the scaled - copy is 5. $\frac{5}{15}=\frac{1}{3}$.

Answer:

C. 1/3
