Question

the floor of a room is 6m 75cm long and 5m

wide It is to be paved with square tiles. Find
the largest size of tile needed.​

Answer 1

Answer:

$lenght \: of \: floor = 6m75cm \\ \: \: \: \: \: \: \: \: \: \: = 675cm$

$breath \: of \: floor \: = 5m \: or \: 500cm$

$area \: of \: floor \: = l \times b$

$675 \times 500$

$= 337500 {cm}^{2}$

$as \: 1 {m}^{2} = 10000 {cm}^{2}$

$so \: \: 337500 {cm}^{2} = 33.75 {m}^{2}$

$so \: answer \: is \: 33.75 {m}^{2}$

Answer 2

Answer:

The Floor of the room = 6m, 75cm long.

1 metre = 100cm so, 6m = 600 cm.

Wide of the floor is = 5cm.

It requires a largest size of tiles to find it we have to take Highest Common Factor ( H. C. F ) of 600, 75 and 5.

Therefore the H. C. F is 5.

So, the largest size of the tiles is 5cm.
