I think you have to find the distance between the two points ( A and A').
There is a formula in coordinate geometry called 'Distance Formula' which is used to find the distance between two points whose coordinates are given.
If A(x1,y1) and A'(x2,y2) are two points then
AA' =
Now A(9,12) & A'(3,6)
So
AA' =
=
=
=
=
