Odpowiedź:
1 ar jest to powierzchnia równa 100 m².
[tex]1 a = 100 m^2 = 0.0001 km^2[/tex]
[tex]1m^2=0.000001km^2[/tex]
[tex]1cm^2=0.0001m^2[/tex]
a) [tex]0.0027 km^2[/tex]
b) [tex]0.00075m^2[/tex]
c) [tex]0.003m^2[/tex]
a)
[tex]27a = 0.0027 {km}^{2} [/tex]
b)
[tex]750 {m}^{2} = 0.00075 {km}^{2} [/tex]
c)
[tex]30 {cm}^{2} = 0.003 {m}^{2} [/tex]
d)
[tex]40 {dm}^{2} = 0.4 {m}^{2} [/tex]
