- A chessboard has 64 squares, each with an area of 4 cm².

- The side length of each square is v4 = 2 cm.

- The length of the whole chessboard (8 squares) is 8 * 2 = 16 cm.

- There's a 2 cm border around the entire chessboard.

- Including the border, the total dimension of the chessboard becomes 16 cm + 2 * 2 cm = 20 cm.

- The perimeter of the chessboard is calculated as 4 * 20 cm = 80 cm.

- Option 4 (80 cm) is the correct answer.
