hiii i needd help on this!!
30.47cm^2=___________mm^2
and
187000 cm^2+ 3.45m^2=_____m^2+_____m^2=________m^2
30.47 cm² = 3047mm²
and
187000 cm² + 3.45m² = 18.7m² + 3.45m² = 22.15 m²
To convert from square centimeters (cm²) to square millimeters (mm²), you need to understand the relationship between the two units.
1 centimeter (cm) is equal to 10 millimeters (mm).
So, 1 cm² is equal to (10 mm)², which is 10² mm² = 100 mm².
To convert 30.47 cm² to mm², you can multiply it by 100. Therefore,
30.47 cm² × 100 mm²/cm² = 3047 mm².
So, 30.47 cm² is equal to 3047 mm².
Now let's solve the second part of the question.
To add the areas in different units, we need to convert them to the same unit first.
187000 cm² can be left as it is since it's already in cm².
To convert 3.45 m² to cm², you need to know the relationship between centimeters and meters.
1 meter (m) is equal to 100 centimeters (cm).
So, 1 m² is equal to (100 cm)², which is 100² cm² = 10,000 cm².
To convert 3.45 m² to cm², you can multiply it by 10,000. Therefore,
3.45 m² × 10,000 cm²/m² = 34,500 cm².
Now we can add the areas:
187000 cm² + 34,500 cm² = 221,500 cm².
Therefore, 187000 cm² + 3.45 m² is equal to 221,500 cm² or 221.5 m².
