Question

A farmer owns a field with an area of 0.34 km2. The farmer buys another field with an area of 34,500 m2. What is the total area of the fields he now owns in km2?

Answer 1

1km^2 = (1000m)^2 = 1,000,000 m^2
So the new field is 0.0345 km^2
Now just add 0.34 + 0.0345

Answer 2

Not a proper use of the metric system, a farmer would state his fields in either ares or hectares.
.34 km^2 = 3400 ares
34,500 m^2 = 345 ares
So now he has 3745 ares or 37.45 hectares

Answer 3

0.13
