Answer :
To find the length of the square living room, we first need to understand that the area of a square is given by the formula: Area = side length squared. In this case, the area of the living room is 256 ft².
To find the side length (which is the same as the length of one side of the square), we need to take the square root of the area. The square root of 256 is 16, so the length of the room is 16 ft.
Therefore, the correct answer is:
- 16 ft
