We know that a square is a quadrangle, all sides of which are equal. According to the condition of the assignment, the perimeter of such a figure is 8 cm. First of all, let us express its side.
P = 4a. Therefore, the second factor is the quotient of the first one:
a = P: 4 = 8: 4 = 2 cm.
The area corresponds to the formula:
S = a² = 2 * 2 = 4 cm².
