4500m2 + 0,1 ha =.........are

4.500 m2 + 0,1 ha ( pake tangga are, kiloare, desiare, dll )
= 4.500 ca + 1.000 are
= 0,45 are + 1000 are
= 1000,45 are
atau
4.500 m2 + 0,1 ha ( pake tangga ... 2 [ contoh = km2 ] )
= 4.500 ca + 100 are
= 0,45 are + 10 are
 100,45 are


Maaf banget ya kalau salah.

100,45 are
semoga membantu
maaf kalo salah
