A campground owner plans to enclose a rectangular field adjacent to a river. The owner wants the field to contain 125,000 square meters. No fencing is required along the river. @ As indicated in the figure above, x represents the length in meters of the fence parallel to the river and y represents the length in meters of the fence perpendicular to the river. Let F represent the total amount of fencing needed in meters. Write an equation for F in terms of x only.. F(x)= Find F'(x) and F"(x). F'(x) = F"(x) = What dimensions (in meters) will use the least amount) fencing? x = X y = m m
