| Let’s find the area of the whole square, knowing that the area of one twelfth of the square is 3 square centimeters. To do this, you need to understand what the area of a square is, namely, that a square is a regular quadrilateral, in which all sides and angles are equal.

The area of a square is equal to the square of its side:

S = a ^ 2.

Since the area of the twelfth part of the square is 3 square centimeters, the area of the whole square is 3 * 12. So let’s calculate the area of the square, we get:

S = 3 * 12 = 36 cm ^ 2.

Answer: S = 36 cm ^ 2.
