The area of the square is 36 cm2. How will its area change in each direction, decrease by 3 times.

The area of the square is calculated by the formula: S = a ^ 2 = 36, where a is the length of the side of the square
So, if you reduce each side of the square by 3 times (in the square, all sides are equal), then
S1 = (a / 3) ^ 2 = (a ^ 2) / 9 = 36/9 = 4, that is, the area of the square will become 4
