Question

Figure B is a scaled copy of Figure A.

Figure A
Figure B
What is the scale factor from Figure A to Figure B?

Answer 1

3:1

Explanation:

figure a= 3 units by 1

Answer 2

Scale factor = 3 : 1

Explanation:

Scale factor of figure =
`\frac{\text{Side length of image}}{\text{Side length of actual}}`

From the graph attached,

Scale factor =
`\frac{\text{Side length of figure B}}{\text{Side length of figure A}}`

=
`(3)/(1)` [Since size of every square of the graph is same]

= 3

Therefore, scale factor of figure A to figure B is 3.

In other words ratio of the size of figure A to figure B will be 3 : 1.
