To measure the area of a soccer field that is 105 meters long and 67 meters wide, the appropriate unit of measure would be square meters (m²).
You can calculate the area using the formula:
\[ \text{Area} = \text{length} \times \text{width} \]
So, in this case:
\[ \text{Area} = 105 , \text{m} \times 67 , \text{m} = 7,035 , \text{m}² \]
Thus, the area of the soccer field is 7,035 square meters.
