Henry owns a cornfield and has placed fences around four poles A, B, C, D. He needs to drive around the field every day to check whether anybody has tried to break in. The four poles are located at:
A(4,5)
B(11,5)
C(11,-4)
D(4-4)
How many miles will Horatio drive if he starts at pole A and drives around the entire border of the field?
