Answer 1

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 $cm^{2}$ = 10×10 $mm^{2}$ = 100 $mm^{2}$

9 $cm^{2}$ = 9×100 $mm^{2}$ = 900 $mm^{2}$

5.2  $cm^{2}$ = 5.20×100 $mm^{2}$ = 520 $mm^{2}$

1 dm = 10 cm

1 $dm^{2}$ = 10×10 $cm^{2}$ = 100 $cm^{2}$

17 $dm^{2}$ = 17× 100 $cm^{2}$ = 1700 $cm^{2}$

4.3 $dm^{2}$ = 4.3 × 100 $cm^{2}$ = 430 $cm^{2}$

1 m = 100 cm

1 $m^{2}$ = 100×100 $cm^{2}$ = 10000 $cm^{2}$

7 $m^{2}$ = 7×10000  $cm^{2}$ = 70000 $cm^{2}$

2.5 $m^{2}$ = 2.5×10000 $cm^{2}$ = 25000 $cm^{2}$

1 km = 1000 m

1 $km^{2}$ = 1000×1000 $m^{2}$ = 1000000 $m^{2}$

50 $km^{2}$ = 50×1000000 $m^{2}$ = 50000000 $m^{2}$

8.5 $km^{2}$ = 8.5×1000000 $m^{2}$ = 8500000 $m^{2}$
