If the area of the garden is 50 ft2, then the area is represented by the formula
50 = l * w
If the length is twice the width, then l = 2w, and
50 = 2w * w ===> 50 = 2w2
Solving for w, we get
w = 5
Now the perimeter of the Fencing is 2w + 2(2w) = 6w, and with w = 5
P = 6(5) = 30.
If the fencing costs $3/ft, then we have
$3/ft * 30 ft = $90
