A standard chessboard does not have any chairs; it consists of 64 squares arranged in an 8x8 grid. However, if you are referring to a chess setup in a tournament or casual play, the number of chairs would depend on the number of players and spectators present, typically one chair per player at the board.
To find out how many chairs were in each row, you can divide the total number of people by the number of rows. Since there were 140 people and the chairs were arranged in 7 equal rows, you divide 140 by 7. This means there were 20 chairs in each row.
If you have 65 chairs with five chairs in each row, you would have a total of 13 rows. This can be calculated by dividing the total number of chairs (65) by the number of chairs in each row (5). The result of 65 divided by 5 is 13 rows.
