120 yards 

4 yards * 7 *2 + 4yards*8*2
56+64=120

thanks @hendirkvbr May I ask where did you get 7 and 8 from?

anonymous · Answer

ok let me try to explain this in good english :p 
well you see the dots right
and u know that the distance between one dot and another is 4 yards
so u have to count  horizontally and vertically how many dot connections u have

and vertically you count 8
do you understand?
