Answer: 6 cm
Step-by-step explanation:
Given: The length of line AB = 15 cm
The scale factor for dilation is 0.4 .
We know that to find the length of the image after dilation ,we need to multiply the scale factor to the dimension of the pre-image.
The length of the image of AB is given by :-
[tex](A'B')=AB\times0.4\\\Rightarrow\ A'B'=15\times0.4\\\Rightarrow\ A'B'=6\ centimeters[/tex]
∴ The length of the image of AB = 6 cm
