If the length of the side of the square is less than 8 cm, then the perimeter of the square is.

Remember that all sides of a square are the same. The perimeter is the sum of all sides.
Square perimeter: square side * 4
1) 8 * 4 = 32 (centimeters)
This means that if the side of the square is 8 cm, then the perimeter is 32 cm.
Let the x side be in our square. Then by condition:
x <8
Means:
P <8 * 4
P <32
Answer: the perimeter of our square can be any number not exceeding 32 centimeters (P <32).
