Answer:
Scale factor = 3 : 1
Step-by-step explanation:
Scale factor of figure = [tex]\frac{\text{Side length of image}}{\text{Side length of actual}}[/tex]
From the graph attached,
Scale factor = [tex]\frac{\text{Side length of figure B}}{\text{Side length of figure A}}[/tex]
= [tex]\frac{3}{1}[/tex] [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.
