## Area of a Rectangle

### Area: Learn

Area is the space within a shape. The units of area are the squares of
the units of length (that is, if a shape's sides are measured in meters,
then the shape's area is measured in *square meters*).

For a rectangle, simply multiply the two different side lengths
(also known as *base* and *height*)
to find the area.

For example, a rectangle with a base of 4 cm and a height of 3 cm has an area of 4*3 = 12 square centimeters.

The diagram below shows how we could count out the 12 square centimeters.

1 | 2 | 3 | 4 |

5 | 6 | 7 | 8 |

9 | 10 | 11 | 12 |

A square is a very special type of rectangle, so the square formula for area is very similar. Where a rectangle has two different side lengths to multiply together, the sides of a square are all the same.
