Answer:
The length of AA' + BB'+CC' is 10.5 cm
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
A translation is a transformation that does not modify the shape or size of the figure. In a translation all the points of the figure will move the same distance and direction.
In this problem
[tex]AA'=BB'=CC'=XY[/tex]
we have that
[tex]XY=3.5\ cm[/tex]
so
[tex]AA'+BB'+CC'=3.5+3.5+3.5=10.5\ cm[/tex]
therefore
The length of AA' + BB'+CC' is 10.5 cm
