The correct options are
A 1 km2
C 100 hm2
1 m2=110,00,000 km2
⇒10,00,000 m2=10,00,00010,00,000 km2 = 1 km2
1 m2=100 dm2
⇒10,00,000 m2=10,00,000×100 dm2 = 10,00,00,000 dm2
1 m2=110,000 hm2
⇒10,00,000 m2=10,00,00010,000 hm2 = 100 hm2
1 m2=10,000 cm2
⇒10,00,000 m2=10,00,000×10,000 cm2 = 10,00,00,00,000 cm2
