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
