Detailed Solution

Given, area of a square is given as 12m2.
The area of any square is always a perfect square numerical value.
But we know that 12 is not a perfect square.
So, of all the given options, we can observe that the second one indicates 12 squares each of side length 1 m. So, 12 squares with side 1 m each will create an area of 12  m 2 .
Hence, the correct option is (2).
