Ali and Tim have 12 sheets of paper that are each 9 inches by
12 inches. They want to use all 12 sheets to make a sign for a
basketball game. They plan to put a strip of cardboard around
the outside edge of the sign. How should they arrange
the 12 sheets of paper to use the least cardboard?
4 in width and 3 in length which will form a square of 36 inches and will have least perimeter.
