Question

the number of tiles of area 0.25msquare required to cover a floor of sides 6m by 5m​

Answer 1

Answer:

Step-by-step explanation:Length of rectangular floor of room= 6m

breadth of rectangular floor= 5m

∴Area of rectangular floor = length* breadth

= 6*5

= 30m2

Side of Square tile= 0.25cm

Now we need to convert Side of Square tile in meters (since unit of all quantity has to be same for ease of calculation)= 0.25/100=0.0025m

Area of square tile = side²

= (0.0025)2

=0.00000625

Now number of tiles required to cover the floor =(area of floor of room)/(area of 1 tile)

= 30/0.00000625

number of tiles required = 4800000 tiles
