Hi there,


It specifically says that 15 feet is the hypotenuse -- it talks about the "perennial" border, *not* the perimeter. Based on the hundreds of math 117 week 7 mathlab checkpoints I have seen (including the figure itself), this is the case.
Therefore the legs are 9 and 12 feet. (because 9^2 + 12^2 = 15^2)
The answers are 9, 12.


Thanks,
Scott
