Answer:
1 cm^2 = 100 mm^2
9 cm^2 = 900 mm^2
5.2 cm^2 = 520 mm^2
1 dm^2 = 100 cm^2
17 dm^2 = 1700 cm^2
4.3 dm^2 = 430 cm^2
1 m^2 = 10000 cm^2
7 m^2 = 70000 cm^2
2.5 m^2 = 25000 cm^2
1 km^2 = 1000000 m^2
50 km^2 = 50000000 m^2
8.5 km^2 = 8500000 m^2
Step-by-step explanation:
1 cm = 10 mm
1 = 10×10
= 100
9 = 9×100
= 900
5.2 = 5.20×100
= 520
1 dm = 10 cm
1 = 10×10
= 100
17 = 17× 100
= 1700
4.3 = 4.3 × 100
= 430
1 m = 100 cm
1 = 100×100
= 10000
7 = 7×10000
= 70000
2.5 = 2.5×10000
= 25000
1 km = 1000 m
1 = 1000×1000
= 1000000
50 = 50×1000000
= 50000000
8.5 = 8.5×1000000
= 8500000
