\(7km^25hm^2=70500dam^2\)

\(7km^25hm^2=\left(7\times10000\right)+\left(5\times100\right)=70500dam^2.\)

5hm2 106m2=606hm2

\(5\text{ hm}^2\text{ }106\text{ m}^2=606\text{ hm}^2\)
 

5hm² 106m²=606 hm²

\(5hm^2=500dam^2\)

\(30000m^2=300dam^2\)

\(20000dm^2=2dam^2\)

\(\Rightarrow500+300+2=802\left(dam^2\right)\)

Gấp lên 150 lần ta được:

\(802\times150=120300\left(dam^2\right)\)
