Based on the image, what is the question being asked about the square?

The question asks: "Чему равны стороны квадрата?" which translates to "What are the sides of the square equal to?"

The image displays a square with side length labeled as 2a.

Additionally, a larger square is shown divided into four smaller rectangles/squares. The sides of this larger square are labeled as 2 and a, and 2 and a, indicating a total side length of 2+a for each dimension. However, the initial question refers to "стороны квадрата" (sides of *the* square) and the first depicted square clearly has sides labeled as 2a.

Answer: The sides of the square are equal to 2a.
