Triangular Island has a lighthouse at each of its corners, represented by the vertices of the triangle. The perimeter of Triangular Island is 6.8 miles. There is a channel on Triangular Island which divides it into two smaller islands: Green Island and Coconut Island. The length of the channel is equal to half of the distance between the lighthouses on Coconut Island. What is the perimeter of Green Island.
