**Area**

The amount of surface enclosed by a closed figure is called its area.

The following conventions are to be adopted while calculating the area of a closed figure using a squared or graph paper.

1. Count the fully-filled squares covered by the closed figure as one square unit or unit square each.

2. Count the half-filled squares as half a square unit.

3. Count the squares that are more than half-filled as one square unit.

4. Ignore the squares filled less than half.

For example, the area of this shape can be calculated as shown:

Covered area |
Number |
Area estimate (sq units) |

Fully filled squares | 6 | 6 |

Half-filled squares | 7 | 7 Ã— Â½ |

Squares filled more than half | 0 | 0 |

Squares filled less than half | 0 | 0 |

Area covered by full squares = 6 Ã— 1 = 6 sq units

Area covered by half squares = 7 Ã— $\frac{\text{1}}{\text{2}}$ = $\frac{\text{7}}{\text{2}}$ = 3$\frac{\text{1}}{\text{2}}$ sq units

Total area of the given shape = 6 + 3$\frac{\text{1}}{\text{2}}$ sq units

Thus, the total area of the given shape = 9$\frac{\text{1}}{\text{2}}$ sq units.

**Area of a rectangle**

Area of a rectangle = length Ã— breadth.

**Area of the square**

Area of the square = side Ã— side.
