The answer is: "12 feet" .
________________________________
Note: In a square, the length of EACH of the four sides of the square is the same.

Area = Length * width.

For a square, length = width.

So for a square, Area = length * width = (length of a side)² = s² ,

Given: A = s² = 144 ft² ;

Solve for the positive value of "s" .
________________________________
→ s² = 144 ft² ; Take the "square root" of each side ;

→ √(s²) = √(144 ft²) ;

→ s = 12 ft.
_______________________________
The answer is: 12 ft.
