# The area of each square on a chess board is 4sqcm. Find the area of the board.

(a) At the beginning of game when all the chess men are put on the board, write area of the squares left unoccupied.

(b) Find the area of the squares occupied by chess men.

Answer :

Area of 1 square = 4 sq.cm

Area of 64 squares = 4 × 64

= 256 sq.cm

(a) Number of chessmen at beginning = 32

Number of squares occupied = 32

Number of unoccupied squares = 32

Area of unoccupied squares = 32 × 4

= 128 sq.cm
