Figure BBB is a scaled copy of Figure AAA. What is the scale factor from Figure AAA to Figure BBB?

The scale factor as a result of transformation from figure A to figure B is;

Scale factor = 1/4

When we talk about scaled copy, it means each dimension of an object is multiplied by same factor known as scaled factor in a process called dilation to arrive at the newly dilated object.

Now, figure B is a scaled copy of figure A.

This means dimensions of figure A have been multiplied by a scale factor to get the dimensions of figure B.

Let us look at corresponding sides.

Length of 4 in figure A is dilated to a length of 1 in figure B.

This means; scale factor y, is gotten by;

4y = 1

y = 1/4
