Answer 2

Answer:

The floor of the room is 8 m long and 6 m wide is to be covered by square tiles. If each square tile is 0.8 m, the number of tiles required to cover the floor is 75, and the cost of tiling at the rate of 12 per tile is 900

Step-by-step explanation:

The length of the floor $l=8m$

the breadth of the floor $b=6m$

since the floor is a rectangle the total area of the floor is $A=l*b$

⇒ $A=8*6=48cm^{2}$

the side of the square tile $a=0.8m$

since the tile is a square the area of one tile $A=a^{2}$

⇒$A=0.8*0.8=0.64cm^{2}$

now the number of tiles is given as the area of the floor divided by the area of one tile

⇒  $\frac{48}{0.64}=75$

the cost of one tile is $12rs/-$

now the total cost of the tile is the product of the total number of tiles and the price of one tile

⇒$12*75=900rs/-$
