The scale factor from figure A to figure B is 1/3.
What is scale factor?
The scale factor is a way to compare figures with similar appearances but differing scales or measurements. Consider two circles that resemble one another but may have different radii. The scaling factor indicates how much a figure has increased or decreased from its initial value.
How to solve the question?
In the question, we are informed that figure B is a scaled copy of figure A.
We are asked to find the scale factor from figure A to figure B.
To find the scale factor, we need to find the dimension of a particular side of figure A, and the corresponding side of figure B, then the ratio of these dimensions gives the scale factor.
Dimension of figure A = 9 units {From the attachment},
Dimension of figure B = 3 units {From the attachment}.
The scale factor is the ratio of the dimension of figure B, to the dimension of figure A.
Thus, the scale factor = 3:9 = 1:3 or 1/3.
Thus, the scale factor from figure A to figure B is 1/3.
