The perimeter of a square is expressed as $4\times S$, where $S$ is a/an .

• A. constant
• B. variable
• C. expression
• D. term

Answer 1

The correct option is B variable

The perimeter of a square is 4 times the length of its side.
Thus, if $S$ stands for the length of the side of the square, $4\times S=4S$ is the perimeter of the square.
Here, $S$ is the variable, 4 is the numerical coefficient of the expression.
