figure a: 4ft and 9ft figure b: 12ft and 27ft
Which scale factor has been applied to figure A to produce figure B?
1/3
3/2
2
3
If a scale factor of 2 is applied to figure A, which of these would be a corresponding side length on the new triangle?
4
12
18
24
The scale factor that has been applied to figure A to produce figure B is 3.
If a scale factor of 2 is applied to figure A, the corresponding side length on the new triangle would be 18.
Explanation:
- Figure A has side lengths of 4ft and 9ft.
- Figure B has side lengths of 12ft and 27ft.
- To go from figure A to figure B, the side lengths were multiplied by a scale factor of 3.
If we apply a scale factor of 2 to figure A:
- The side length of 4ft in figure A would be 4ft x 2 = 8ft in the new triangle.
- The side length of 9ft in figure A would be 9ft x 2 = 18ft in the new triangle.
