Answer 2

Answer:

$\boxed {\tt 36 \ centimeters}$

Step-by-step explanation:

The perimeter is the sum of all the side lengths and a square has 4 equal sides.

The perimeter of a square can be found by adding the side length 4 times or multiplying the side length by 4.

$p=4s$

The side length is 9 centimeters.

$s= 9 \ cm$

Substitute the value into the formula.

$p=4(9 \ cm)$

Multiply

$p= 36 \ cm$

The perimeter of a square with a side length of 9 centimeter is 36 centimeters.
