A retangular poster is to be made out of cardboard. The margins on the top and the bottom will be 2 inches. The margins on the sides will be 1 inch. The area of the poster devoted to the printed material must be 300 square inches.

(a) to the nearest .001 inches, find the dimensions of the poster that use the least amount of cardboard.

(b) To the nearest .001 square inches, find the area of the poster that uses the least amount of cardboard.

I know the Area of a rectange = Length X Width. But for part a basically it's converting square inches to inches
