Question

how many square tiles of side 30 cm will be required to fit in a rectangular hall o length 15 m and breadth 12 m

Answer 1

Answer:

Step-by-step explanation:

Length of a rectangular hall L=40 m

Breadth of the rectangular hall B=18 m

So, the area of hall

=L×B=40×18=720 m  

2

 

Since,

Length of tiles l=1 m

Breadth of tiles b=50 cm=0.5 m

So, the area of each tile

=l×b=1×0.5=0.5 m  

2

 

Therefore, the numbers of tiles are required

=  

0.5

720

​  

=1440

Answer 2

Answer:

2,000 TILES ARE REQUIRED!!!

Step-by-step explanation:

AREA OF 1 SQUARE TILE = (a)²

                                           = (30cm)²

                                           = 900cm²

AREA OF RECTANGULAR HALL = LENGTH * BREADTH

                                                      = 15m*12m

                                                      = 180m²

NUMBER OF TILES REQUIRED = 180m²/900cm²

                                                    = 180*100*100cm²/900cm²

                                                    = 2,000 TILES

SO,

2000 TILES ARE REQUIRED
