You can't tell the dimensions from the area. There are an infinite number of correct answers. The length of the fence is 2 times (length of the pond + width) and the length and width can be anything, just as long as their product is 2956.5 .
F(t)=30 sin(pi/3 t)-15
when sin(pi/3 t) = 1, f(t) = 15 => max.
when sin(pi/3 t) = -1 f(t) = -45 .+ min.
period = 2π / (π/3) = 6 hrs.
(54.3+56.1+n)/3 = 55
54.3+56.1+n = 165
54.6 = n
