a) AB: length of tile
width of tile : length of tile
1:2
3 units -> 12 cm
1 unit -> 4 cm
AB = 4 cm x 2 = 8 cm
b) 1 small block with AB as length (8 cm) and width of 12 cm contains 3 tiles
length of 880 cm will contain 880 / 8 = 110 blocks
110 blocks = 110 x 3 = 330 tiles
width of tile : length of tile
