Answer:
The margin of error is 
Step-by-step explanation:
From the question we are told that
The sample size is 
The sample mean is 
The standard deviation is 
Given that the confidence level is 95% the the level of significance can be evaluated as



Next we obtain the critical value of
from the normal distribution table,the value is 
Generally the margin of error is mathematically represented as

substituting values


Since it is area the best measurement would be square meters.
