We want area A.
A = LW
We know the fence is a rectangle with only three sides. We know the two lengths of the fence, 2L, and the width of the fence, W, add up to 220.
2L + W = 220
Alternatively, W = -2L + 220. We'll substitute this into A = LW:
A = L(-2L + 220) = -2L^2 + 220L
A = -2L^2 + 220L is a quadratic equation graphing the area of a fence with L length. The maximum or minimum of a quadratic equation (in this case, maximum) is -b/2a (a and b being the first two terms of the equation), so the maximum length is -220/-4 = 55.
A = 55 x 110 = 6050
6050/11 + 3 = 553, or Krookodile.
