The area is increased by a factor of 9.
I assume you mean the relationship between the length and the area. Indeed, it is non-linear. The increase in area is proportional to the square of the length of the side. For example, if the length of the side is increased by a factor of 10, the area is NOT increased by a factor of 10, but by a factor of 100.
The error in its area is then 2 percent....
It is increased by x sqrt(2).

The area is increased to 22 = 4 times what is was.The area is increased to 22 = 4 times what is was.The area is increased to 22 = 4 times what is was.The area is increased to 22 = 4 times what is was.
Each side is multiplied by 3, so the area is multiplied by 9, so the answer is 90.
The area of a square is the square of its side length.
