Question

PLEASE HELP!!!!!!! Figure B is a scaled copy of Figure A. What is the scale factor from Figure A to Figure B?

Answer 1

4
To find the scale factor, we need to know what number we multiply each side length in Figure AAA by to get the corresponding side length in Figure BBB.

Let's see how the corresponding sides relate:

10×4

11×4

18×4

​

=40

=44

=72

​

Answer 2

1:4

Explanation:

Find the ratio of corresponding sides

`(10)/(40)=(1)/(4)\\\\\\(11)/(44)=(1)/(4)\\\\\\(18)/(72)=(1)/(4)\\\\\`

Scale factor:

1:4
