🟦 Tile the Floor
Why is area rows × columns?
Area is how much floor a shape covers. Two pens have the same length of fence. Do they hold the same number of tiles? Let’s cover them and count.

“Both fences are 16 long. So both pens hold the same!”
The fence measures around the pen.

A rectangle is rows of equal squares, so you don’t have to count them one by one: rows × squares in each row, or length × width. If each square is 1 cm on a side, the answer is in square centimetres (cm²). The fence around the outside is a different measure: two pens with the same fence can hold very different areas, and the squarest one holds the most.
