Answer:
10 square meters will have a standard deviation of 1.897.
Step-by-step explanation:
Standard deviation for n instances of a variable:
If the standard deviation for one instance of a variable is 
, for n instances of the variable, the standard deviation will be of 
The standard deviation of the number of flaws per square yard is 0.6
This means that 
For the 10 square yards will a standard deviation of
, so:
10 square meters will have a standard deviation of 1.897.
-45.6 is the answer if you evaluate
