Question

the floor of a hall is 20 m long and 15m wide. find the number of tiles required to cover the floor if the dimension of one tile is 20 cm * 10 cm.​

Answer 1

Answer:hi mate here is ur answer

Step-by-step explanation:

Area of floor =l×b

                  = 20 m ×15 m

                   = 300 sq m

Dimensions of tiles are 20×10

Area covered by one tile = 20×10

                                      = 200 sq cm

300 sq m = 300×100×100 sq cm [1sqm = 100×100 sq m]

Number of tiles = 300×100×100/200

                       =15000 tiles

Answer 2

Answer:

Total 15,000 tiles would be required.

Step-by-step explanation:

first convert 20m into cm = 2000cm

15m into cm = 1500cm

area of hall=length x breadth

area=(1500 x 2000)cm²

area=30,00,000cm²

area of each tile=(20 x 10)cm²

area=200cm²

so no.of tiles required = area of hall/area of each tile

no.of tiles=30,00,000/200

no.of tiles=15,000
