Rotation of 180° about the origin
Answer:
369.47 ft
Step-by-step explanation:
Each plot is 1/10 of the total length, so has length ...
(3694.7 ft)/10 = 369.47 ft
A = L * W = 75 so L = 75/W Cost = 4W + 8(2L + W) = 4W + 16L + 8W = 12W + 16L = 12W + 1200/W C' = (12(W^2 - 100))/(W^2) = (12(W-10)(W+10))/(W^2) so W = 10 then L = 7.5
