Eight identical rectangular tiles are used to form a rectangular floor. The tiling method and relevant data are shown in the figure. The length and width of each tile are calculated

Suppose the length of each tile is xcm and the width is YCM. According to the meaning of the question, we get x + y = 60x = 3Y. Solving this equation, we get x = 45y = 15. Answer: the length of each tile is 45cm and the width is 15cm;
