The length of C'A' is 10 units, the correct option is A.
What is Dilation?
Dilation is the process of enlarging or compressing a figure. The factor by which this process happens is called the scale factor.
Triangle ABC is dilated by the rule Dy, 5/4
If measure of CA = 8
The length of C'A' will be determined by using the formula of scale factor
Scale factor = Dimensions of new figure/ Dimensions of original figure
Here,
Scale factor = C'A' / CA
(5/4) x CA = C'A'
C'A' = (5/ 4) x 8
C'A' = 10 units
