Area of the garden =200 square feet
Let the dimensions of the garden be x and y
Area, xy=200
Since one side is already protected by a barn,
Perimeter of the garden=2x+y
The minimum point of P(y) is the point where its derivative equals zero.
y=20feet
Recall:
xy=200
20x=200
x=10feet
The dimensions of the garden that will require minimum fencing is 20 ft by 10ft
