Perimeter of triangle = Sum of all sides =

Now you can see its pretty simple, its 128 but the way i got it is first you double 8 which makes 16 right then double 16 and you can see you got 32 then double 32 which makes 64 so next what you have to do is double 64 Obiously so you just double those numbers to get 128....Get it?
Answer:
maybe y= 9 because side A B is 10 and side C D is almost the same just sleep slightly shorter.
If they're travelling towards each other;
Effective speed = 75+55 = 130
Distance = 338m
Time= distance/ speed
T= 338/130
T= 2.6 hrs
