The formula for the perimeter of a square is P = 4s, where P is the perimeter and s is the length of one side of the square. If the perimeter is equal to 44 cm, we can set up the equation:

44 = 4s

To find the length of one side of the square, we can divide both sides of the equation by 4:

s = 11

Now that we know the length of one side of the square is 11 cm, we can use the formula for the area of a square, which is A = s^2, to find the area of the square:

A = s^2

A = 11^2

A = 121 cm²

So the answer is А. 121 см²

P=4a

a=P:4=44:4=11 см

S=a²

S=11²=121 см²
