Answer 3

Solution:

To solve this problem, we can use algebra to represent the relationship between the number of squares Olga cut and the number of squares Tetyana cut.

Let's denote the number of squares Olga cut as O and the number of squares Tetyana cut as T. We are given that Olga cut 12 squares and Tetyana cut 4 squares less than Olga.

We can represent this relationship with the equation: T = O - 4

Now, we can substitute the given value of Olga's squares into the equation and solve for Tetyana's squares.

Calculation:

Given: - Olga cut 12 squares.

Using the equation T = O - 4, where O = 12: T = 12 - 4 T = 8

Answer:

Tetyana cut 8 squares.
