Question

how many tiles 6dm by 5dm will be required to cover the floor of a room 40m by 15m

Answer 1

Answer:

Step-by-step explanation:

l =40m

b=15 m

area of verandah[rectangle]=l*b

                                            =40m*15m

                                            =600m.sq

and stone each measuring 6dm by5dm

by converting it into meter we get,

   0.6m by  0.5m

now, area of stone= l*b

                             =0.6m*0.5m

                             =0.3m.sq

now, number of stone required =area of verandah/area of stone

                                                 =600m.sq/0.3m.sq

                                                 =600*10/3

                                                 =6000/3

                                                  =2000.  

done! may you got use of this ....
