Answer:
[tex]5*10^{8}cm^{2}[/tex]
Explanation:
First you put in order the information the problem gives you:
* 1 ha = 10000[tex]m^{2}[/tex]
* The farm has 5 ha
Then you use a conversion factor:
1)* The farm has 5 ha:
[tex]5 ha[/tex]
2) Multiply by the equivalence of ha in meters:
[tex]5ha*\frac{10000m^{2}}{1ha}[/tex]
3) Solve:
[tex]5ha*\frac{10000m^{2}}{1ha}=50000m^{2}[/tex]
Finally you should convert from [tex]m^{2}[/tex] to square centimeters [tex]cm^{2}[/tex],so:
[tex]50000m^{2}*\frac{10000cm^{2}}{1m^{2}}=5*10^{8}cm^{2}[/tex]
