Area
Area is the space inside a flat shape. Count the squares inside the shape.
For a rectangle on a grid there is a shortcut: count the squares in one row and multiply by the number of rows. 5 squares in a row × 3 rows = 15 squares.
Area units are square: cm², m². Don’t mix it up with perimeter.
On a grid
Count the whole squares, then match up the half squares: two halves = one whole. Example: a shape covers 8 whole squares and 4 half squares, so its area = 8 + 2 = 10 squares.
Remember this and test yourself
- Area = space inside a shape.
- Area: count the squares inside the shape.
