Jamila keeps alpacas on a 1-acre, square lot near her home. She has 6 alpacas and wants to build a fence diagonally to split the herd in two. If an acre is 209 feet long, how many feet, to the nearest foot, of fencing does Jamila need?
The length of one side of the square lot is the square root of the area, 1 acre * 209 ft/acre = <<1*209=209>>209 feet
The length of the diagonal fence is 209 feet * sqrt(2) = <<209*sqrt(2)=295.98489827516287>>295.98 feet rounded to the nearest foot. Answer: \boxed{296}.
