Answer:
is the required domain.
Step-by-step explanation:
We have been given two squares
Let the larger square area be x
We have been given the area of smaller square we need to find the domain of area of larger square.
Domian is the value that x can take in a function
Here, x is the area of the larger square
Since, area of smaller square is 
The area of larger circle has to be greater than 
The domain will be all real numbers grater than 10
Mathematically,
is the required domain.
