To answer this, we need to know the expression for the area of a square which is the square of its side length or:

Area = a²

Solving for the side length,

a = √area
a = √144x²
a = 12x

Therefore, the side length is 12x.

Answer:

If the area of the square is 144x^2, then the side length would be 12x.

Short Explanation:

Considering 12 * 12 is equal to 144, and the fact that the 'x' variable is unknown, then we can write the side length as 12, or in this case 12x.
