Considering all rectangles with a given perimeter, which one encloses the largest area? The traditional calculus approach would be as follows. Letting P equal the given perimeter and "x" the short side of the rectangle, we can write for the area A = x(P - 2x)/2 = Px/...

I largest area of a rectangle is obtained when that rectangle is a square, so x^2 = 48 x = √48 = 4√3 = appr 6.9 or 7 as a whole number. She will need 4(7) or 28 ft of fencing If the rectangle is 6 ft by 8 ft, then the area will be exactly 48 ft^2 and the ...

If we use h and w for length and width, with length parallel to the road, perimeter p = 2w+h = 248 Area = w*h = w(248-2w) = 248w - 2w^2 We want to maximize the area, so we take the derivative and set it to zero. 248-4w = 0 w = 62 So, h = 124 Maximum area = 62*124 = 7688 sq ft ...
