Question

The side of a square is x units. Which one of following expressions represents the perimeter?
x + x + x + x = 4x
x + x = 2x
x*x = 2x
x + x + x = 3x

Answer 1

The perimeter \( P \) of a square is calculated by adding the lengths of all four sides. Since each side of the square is \( x \) units long, the expression for the perimeter is:

\[
P = x + x + x + x = 4x
\]

So, the correct expression that represents the perimeter of the square is \( 4x \).
