Length of board (L) = 100cm = 1m
Breadth of board (B) = 200cm = 2m

Area of rectangular board = L × B
                                          = 1m × 2m 
                                          = 2 m²

Cost of painting= $9 per m²

Therefore cost of painting whole board = 9 × 2 = $ 18

Hope my answer helps u.
