Based on the base of the cross-country course and its side length, the total length of the cross-country course is 10 miles.
The cross-country course is shaped as a parallelogram which means that the total length is the same as the perimeter of the parallelogram.
The total length therefore is:
= 3 + 3 + 2 + 2
= 10 miles
In conclusion, the total length of the cross-country course is 10 miles.
