In the decimal metric system, we must remember that in the transformation of surface units, **each surface unit is 100 times larger than the next lower unit**:

Note the following transformations:

transform 2.36 m

^{2}in mm^{2}.

km^{2} | hm^{2} | dam^{2} | m^{2} | dm^{2} | cm^{2} | mm^{2} |

To transform m^{2} in mm^{2} (**three** positions to **right**) we must multiply by 1,000,000 (100x100x100).

2.36 x 1,000,000 = 2,360,000 mm^{2}

turn 580.2 dam

^{2}in km^{2}.

km^{2} | hm^{2} | dam^{2} | m^{2} | dm^{2} | cm^{2} | mm^{2} |

To turn dam^{2} in km^{2} (**two** positions to **left**) we should divide by 10,000 (100x100).

580.2: 10,000 = 0.05802 km^{2}

**Practice it! Try to solve these exercises:**

1) Transform 8.37 dm^{2} in mm^{2} (R: 83,700 mm^{2})

2) Transform 3.1416 m^{2} in cm^{2} (R: 31.416 cm^{2})

3) Transform 2.14 m^{2} in dam^{2} (R: 0.0214 dam^{2})

4) Calculate 40m x 25m (R: 1,000m^{2})
