A farmer owns a field with an area of 0.23 km2. The farmer buys another field with an area of 45,000 m2. What is the total area of the fields he now owns in km2?

Answer 1

If

1km=1000m
1km²=1000000m²

1m²=1km²/1000000

45000m²=(45000km²)/1000000=0.045km²

0.23km²+0.045km²=?

Answer 2

I know I'm very late but the answer should be 0.275 (km^2)
