Growing rectangles: Suppose we are growing rectangles - specifically rectangles in which one side is 1 unit longer than the other. Create a table that shows the height and number of tiles in the rectangles up to a height of 10. What might a graph of this table look like?
What equation will generate the number of tiles for a height of n? Use the diagrams (you can expand them) and the table to show how you arrived at your equation.
