Question

Bob wants to cover the floor of a room 3 m wide and 4 m long
by squared tiles. If each square tile is of side 0.5 m, then find the number of tiles required to cover the floor of the room.​​

Answer 1

Step-by-step explanation:

Total Area of the floor = 3×4 m² = 12 m²

Area of each tile= 0.5×0.5 m² = 0.25 m²

Therefore Required number of tiles = 12/0.25 = 48

( In the given question ), Bob wants to cover its floor of a room is 3m wide and 4m long by squared tiles. Each square tiles is of side 0.5m, And we have to find the number of tiles to cover the floor.

__________________________________

$\huge\bold{Let's\:solve}$

__________________________________

Total area of tiles must be equal to the area of the floor of the room.

$\large \sf { Length \:of\:the\:room\:=\:4m}$

$\large \sf { Breadth \:of\:the\:room\:=\:3m }$

$\large \sf { Area\:of\:the\:floor\:=(L×B) }$

$\large \sf { =4m\:×\:3m=\:12sq\:m }$

$\large \sf { Area\:of\:1\:square \:tile=\:Side×Side}$

$\large \sf { =0.5m\:×\:0.5m }$

$\large \sf { =\:0.25sq\:m }$

$\large \sf number \: of \: tiles \: = \frac{area \: of \: the \: floor}{area \: of \: one \: tile}$

$\large \sf = \frac{12}{0.25} = \frac{1200}{25} = 48 \: tiles$
