Answer: The required value of A is 2 square units.
Step-by-step explanation: We are given the following values for s and A :
\(s=\dfrac{1}{3}~\textup{unit}~~~~\textup{and}~~~A=18s^2.\)
We are to find the value of A in square units.
To find the value of A, we need to substitute the value of s in the expression for A.
Therefore, we get
\(A=18s^2=18\times\left(\dfrac{1}{3}\right)^2=18\times\dfrac{1}{9}=2~\textup{sq. units}.\)
Thus, the required value of A is 2 square units.
