Five feet, because five times four is 20.
$90If the area of the garden is 50 ft2, then the area is represented by the formula50 = l * wIf the length is twice the width, then l = 2w, and50 = 2w * w ===> 50 = 2w2Solving for w, we getw = 5Now the perimeter of the fencing is 2w + 2(2w) = 6w, and with w = 5P = 6(5) = 30.If the fencing costs $3/ft, then we have$3/ft * 30 ft = $90
The biggest diameter that would fit is 20 ft.
