Answer: $66

Step-by-step explanation:

Area of a rectangular =length*breadth

= 3.2 km * 3.0 km = 9.6km(squared)

Note, 1.6km = 1 mile

Cost of a hiking trail = $11 per mile

Converting kilometer to kill = 9.6km/1.6km = 6 miles

Hence, cost of a hiking trail to surround the rectangular shaped wilderness = $11 * 6 = $66

In case the cost is $11,000 per mile; total cost of hiking trails to surround the wilderness equals $66,000
