Question

A floor is 4.5 m long and 5.6 m wide.A 6 cm long tile costs rs 23.25 what will be the cost to cover the floor with these tiles

Answer 1

Area of the floor is length*breath

So, 4.5m*5.6m = 25.2msqu

Convert 6cm into m = 6*0,01 = 0.06m

25.2msqu÷0.06m = 420m

Rs of 0.06m = 23.25$

So 420m*23.25 = 9870$

Answer 2

Answer:

A floor 4.5m long and 5.6m wide is to be covered with tiles. A 6cm square tile costs rs.23.25, the cost to cover the floor with these tiles is 162750 rupees

Step-by-step explanation:

The length of the floor $l=4.5m=450cm$

the breadth of the floor $b=5.6m=560cm$

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

⇒ $A=450*560=252000cm^{2}$

the side of the square tile $a=6cm$

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

⇒$A=6*6=36cm^{2}$

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

⇒  $\frac{450*560}{36}=7000$

the cost of one tile is $23.25rs/-$

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

⇒$7000*23.25=162750rs/-$
