A youth group is setting up camp. Rain is predicted, so the campers decide to build a fly, or rain cover, over their tent. The f
inessss [21]
Most of the information's required for finding the answer is already given in the question. 
Height of the fly = 12 feet
Width of the fly = 16 feet
Now we can find the length of the poles using Pythagoras theorem.

Length of the poles = square root [(12)^2 + (8)^2]
                               = square root (144 + 64)
                               = square root (208)
                               = 14.4 feet
From the above deduction, we can conclude that the height of the poles needed to be 14.4 feet. I hope the answer has helped you.
