Chessboard Perimeter Calculation

To calculate the perimeter of the remaining figure after Vasya removed the white cells at the edges of the chessboard, we can use the following approach:

1. Identify the Size of the Chessboard: - The chessboard is described as having a size of N * N cells.

2. Determine the Perimeter of the Remaining Figure: - After removing the white cells at the edges, the perimeter of the remaining figure can be calculated by considering the number of cells left on the edges of the chessboard.

Based on the provided information, the specific calculation for the perimeter can be derived from the size of the chessboard and the removal of the white cells at the edges.

Let's proceed with the calculation.

Calculation

The perimeter of the remaining figure can be calculated using the formula: \[ \text{Perimeter} = 4 \times (N - 2) \]

Where: - N represents the size of the chessboard.

Result

Using the given size of the chessboard, the perimeter of the remaining figure after removing the white cells at the edges is: \[ \text{Perimeter} = 4 \times (N - 2) \]

This formula accounts for the removal of the white cells at the edges, resulting in the calculation of the perimeter of the remaining figure.
