25 cm2=?gm2 4.5m2=?km2

Answer 1

0.00000000025
0.0000004

Answer 2

To convert square centimeters (cm²) to square meters (m²), you need to divide by 10,000 (since there are 10,000 cm² in 1 m²). Similarly, to convert square meters to square kilometers (km²), you need to divide by 1,000,000 (since there are 1,000,000 m² in 1 km²).

Let's perform the conversions:

1. 25 cm² to m²: 25 cm² / 10,000 = 0.0025 m²

Therefore, 25 cm² is equal to 0.0025 m².

2. 4.5 m² to km²: 4.5 m² / 1,000,000 = 0.0000045 km²

Therefore, 4.5 m² is equal to 0.0000045 km².
