Answer:
19 miles
Explanation:
Given that :
Shape of route is rectangular :
Length of route = 5.5 miles
Width of route = 4 miles
Distance of one complete trip = perimeter of the rectangular route :
Perimeter of a rectangle :
P = 2(length + Width)
P = 2(5.5 + 4)
P = 2(9.5)
P = 19 miles
Hence one complete trip is 19 miles long.
