Observe the changes to the rectangle as you adjust the "length" and "width" sliders. Each square in the grid is 1cm by 1cm.

Questions:
1. Adjust the sliders so l = 5 and w = 3. How many squares fit inside the rectangle?
2. Adjust the sliders so l = 5.5 and w = 3. How many squares fit inside the rectangle now?
3. When we say that the area of the rectangle is "32 square cm" or "32 cm squared", what do we really mean by that?
4. What measurements of the rectangle would give you an area of 32 square cm?
5. What is the formula for the area of a rectangle? Your answer should be in terms of l and w.
