Noah would like to cover a rectangular tray with rectangular tiles. The tray has a width of inches and an area of square inches. Find the length of the tray in inches. If the tiles are inch by inch, how many would Noah need to cover the tray completely, without gaps or overlaps? Explain or show your reasoning. Draw a diagram to show how Noah could lay the tiles. Your diagram should show how many tiles would be needed to cover the length and width of the tray, but does not need to show every tile.
