Using unit squares, we'll measure their areas, emphasizing the importance of a unit square for measuring various shapes.

For example, if you walk around the edge of a playground, you're measuring its perimeter. Area is the amount of space inside a shape. For example, if you want to put new tiles on your kitchen floor, you need to know the area of the room to know how many tiles to buy.
