How is the area of a square calculated?

2s
s², where s is the length of a side
πs
s + s

The correct answer is: s², where s is the length of a side

The area of a square is calculated using the formula $ s^2 $, where $ s $ represents the length of one side of the square. This formula derives from the definition of area as the amount of space contained within a two-dimensional shape. In the case of a square, which has four equal sides, the area is obtained by multiplying the length of one side by itself. For example, if one side of the square is 4 units long, the area would be $ 4 \times 4 = 16 $ square units. This makes option B the correct choice, as it accurately reflects the geometric principles involved in calculating the area of a square. The other options do not represent the area of a square. The expression $ 2s $ pertains to the perimeter of the square, not its area. The term $ πs $ is related to circles, as it includes the mathematical constant π, which is not relevant to the area of a square. Lastly, $ s + s $ simplifies to $ 2s $, which again refers to the perimeter, further emphasizing that these choices do not address the area of the square accurately.
