If the lake is a perfect circle the circumference would be 2 pi r, or 2,224.25 feet. Lakes aren't perfect circles so the circumference is probably much larger.

p + O = 60 . . . so . . . p = 60 - O5p + 8O = 354Substitute [ p = 60 - O ]:5(60-O) + 8O = 354300 - 5O + 8O = 354300 + 3O = 3543O = 54O = 18p = 60 - O = 42Pentagons: 42Octagons: 18===========================Check:p + O = 42 + 18 = 60Sides on pentagons = 5 x 42 = 210Sides on octagons = 8 x 18 = 144Sum of sides = 210 + 144 = 354 yay!
