You want to form a rectangular pen of area, a = 60 ft2 (see the figure below). One side of the pen is to be formed by an existing building and the other three sides by a fence. If w is the width of the sides of the rectangle perpendicular to the building, then the length of the side parallel to the building is L = 60/w. The total amount of fence required is the function F = 2w + 60/w, in feet.

Determine the dimensions of the rectangle that requires a minimum amount of fence. Round to two decimal places.

Width= ________ feet

Length= _________ feet
