Question

7 a rectangular hall is 12 metre long and 6 metre board.its flooring is to be made of su
square tile of side 30 CM how many​

Answer 1

Answer:

60 tiles will fit in the hall.

Step-by-step explanation:

to get the number of tiles, we should change the length and breadth to cm.

1m-100cm

12X100=1200

6X100=600

1200+600=1800

1800÷30=60

=60 tiles

Answer 2

Step-by-step explanation:

dimension of hall :

dimension of hall : length = 12 m

dimension of hall : length = 12 mbreadth= 6 m

Therefore area of the Hall : 72m²

Therefore area of the Hall : 72m²Now 72 m²= 720000 cm²

Therefore area of the Hall : 72m²Now 72 m²= 720000 cm²[ 1 m². =. 10000 cm²]

Therefore area of the Hall : 72m²Now 72 m²= 720000 cm²[ 1 m². =. 10000 cm²][ therefore 72 × 10000 cm²]

Therefore area of the Hall : 72m²Now 72 m²= 720000 cm²[ 1 m². =. 10000 cm²][ therefore 72 × 10000 cm²][ = 7,20,000 cm²]

Therefore area of the Hall : 72m²Now 72 m²= 720000 cm²[ 1 m². =. 10000 cm²][ therefore 72 × 10000 cm²][ = 7,20,000 cm²]Now area of the square tile = a²

Therefore area of the Hall : 72m²Now 72 m²= 720000 cm²[ 1 m². =. 10000 cm²][ therefore 72 × 10000 cm²][ = 7,20,000 cm²]Now area of the square tile = a² = 30× 30

Therefore area of the Hall : 72m²Now 72 m²= 720000 cm²[ 1 m². =. 10000 cm²][ therefore 72 × 10000 cm²][ = 7,20,000 cm²]Now area of the square tile = a² = 30× 30 = 900cm²

Therefore area of the Hall : 72m²Now 72 m²= 720000 cm²[ 1 m². =. 10000 cm²][ therefore 72 × 10000 cm²][ = 7,20,000 cm²]Now area of the square tile = a² = 30× 30 = 900cm²therefore no of tiles = 720000 ÷ 900

Therefore area of the Hall : 72m²Now 72 m²= 720000 cm²[ 1 m². =. 10000 cm²][ therefore 72 × 10000 cm²][ = 7,20,000 cm²]Now area of the square tile = a² = 30× 30 = 900cm²therefore no of tiles = 720000 ÷ 900 = 800 tiles
