Answer:
52 miles
Step-by-step explanation:
A to B:
sqrt( (3 - (-2))^2 + (-11 - 1)^2 )
sqrt( (5)^2 + (-12)^2 )
sqrt( 25 + 144 )
sqrt( 169 )
13
B to C:
sqrt( (-2 - 3)^2 + (-23 - (-11))^2 )
sqrt( (-5)^2 + (-12)^2 )
sqrt( 25 + 144 )
sqrt( 169 )
13
C to D:
sqrt( (-7 - (-2))^2 + (-11 - (-23))^2 )
sqrt( (-5)^2 + (12)^2 )
sqrt( 25 + 144 )
sqrt( 169 )
13
D to A:
sqrt( (-2 - (-7))^2 + (1 - (-11))^2 )
sqrt( (5)^2 + (12)^2 )
sqrt( 25 + 144 )
sqrt( 169 )
13
Adding:
13 + 13 + 13 + 13
52
