Answer:
4.) 12ft 
Step-by-step explanation:
You solve the area of a square using the following equation: 
Area of a square = <em>s</em>²
Plug in 144 for Area of a square: 
144 = s²
Isolate the variable, s. Root both sides of the equation. 
√144 = √s²
s = √144 = √(12 * 12) = 12
4.) 12ft is your answer.
