The length and breadth of a hall are 21



m and 11



m, respectively. How many tiles

are required to pave the floor of the hall if square tiles of side



m are used?
​

Answer 1

Answer:

231 tiles are to be used

Step-by-step explanation:

area of the floor= 231 m sq

area of each tile = 1m sq

therefore, no of tiles= area of floor/ area of tile

                                 =>231/1

                                 = 231 tiles
