**calculus?**

assuming the garage will be one of the long sides (otherwise lots of extra fencing will be used), then if the long side is x, the short side will be 50/x. So, the amount of fence, f, is f(x) = x + 2(50/x) = x + 100/x df/dx = 1 - 100/x^2 we want minimum fence, so df/dx = 0: x...

let the length be x let the width be w but 2x + 2w = 240 x + w = 120 w = 120-x area = xw = x(120-x) = -x^2 + 120x d(area)/dx = -2x + 120 = 0 for a max of area -2x = -120 x = 60 then w = 120-60 = 60 for the max area the rectangle should be a square of 60 ft by 60 ft for a max ...
