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
 = 10×10  = 100
 = 100  
 
9  = 9×100
 = 9×100  = 900
 = 900 
5.2   = 5.20×100
 = 5.20×100  = 520
 = 520 
1 dm = 10 cm
1  = 10×10
 = 10×10  = 100
 = 100 
17  = 17× 100
 = 17× 100  = 1700
 = 1700 
4.3  = 4.3 × 100
 = 4.3 × 100  = 430
 = 430 
1 m = 100 cm
1  = 100×100
 = 100×100  = 10000
 = 10000 
7  = 7×10000
 = 7×10000   = 70000
 = 70000 
2.5  = 2.5×10000
 = 2.5×10000  = 25000
 = 25000 
1 km = 1000 m 
1  = 1000×1000
 = 1000×1000  = 1000000
 = 1000000 
50  = 50×1000000
 = 50×1000000  = 50000000
 = 50000000 
8.5  = 8.5×1000000
 = 8.5×1000000  = 8500000
 = 8500000
