Question

Which unit of measure would be appropriate for the area of a soccer field that is 105 m long and 67 m wide

Answer 1

An appropriate unit of measurement for the area of the a soccer field is meters. It could never be miles, because that's way too long. Or millimeters, because that's way too short. Soccer fields are usually meters and meters long, so a unit of measure that is appropriate for an area of a soccer field is meters.
