Asked by Ismail

Alex wants to decorate her bedroom wall with colored square paper. She wants all the squares to be the same size to make a checkerboard design. The area to tile is a rectangle measuring 80 inches by 96 inches. The paper squares come in widths of 10in, 12in, 16in and 20in.
Which size tile do you recommend Alex buys? Explain or show your reasoning for this choice.
Answered by R_scott
the 80 and 96 inches should both be a whole number multiple of the paper square size

only one size works
