Answer 2

Step-by-step explanation:

length of the room is 680cm

breadth of the room is 320 CM

area of the room =680 *320=217600 centimetre square

area of 1 square tile is 40 * 40(cm)=1600 CM square

number of tiles required = area of room / area of tile=21 7600 /1600=136

so 136 tiles are required .
