The side of a square is 2 cm. What is its perimeter?

Before proceeding with the solution, let’s recall the definition of a square:

A square is a four-sided geometric figure in which all four sides are equal.

The perimeter (usually denoted by the letter P) is the sum of all the sides of a geometric figure.

So, the side of the square is 2 cm, the perimeter is the sum of all sides, and the square has four sides. It turns out that you need to fold the four sides of the square, and since it has four sides of the same, you need to fold 2 cm four times:

P = 2 cm + 2 cm + 2 cm + 2 cm;

P = 8 cm;

Answer: 8 cm.
