Question

Ram wants to cover the floor of a room 5m wide and 8m long by squared tiles. If each square tile is of the side 0.5m, then find the number of tiles required to cover the floor of the room.​

Answer 1

Given :-

dimensions of the rectangular floor :-

• length (long) = 8m

• breadth (width) = 5m

dimension of the square tile :-

• side = 0.5m

here, we've to find the no. of square tiles required to cover the rectangular floor.

to find it's no. we have to divide the area of the rectangular floor by the area of the square tile.

we know that,

formula to find the area of a rectangle = length × breadth

formula to find the area of a square = side × side

therefore no. of square tiles required to cover the floor = (8 × 5)/(0.5 × 0.5)

= 16 × 10

= 160 tiles

hence, 160 square tiles are required to cover the floor.

Answer 2

Length of square tile = 8 m

Breadth of square tile = 5 m

Side of square tile = 0.5 m

___________ [ GIVEN ]

• We have to find the number of tiles required to cover the floor of the room.

_____________________________

Now...

» Area of tile = side × side

=> 0.5 × 0.5

=> 25/100 m²

=> 0.25 m²

____________________________

Now..

Area of rectangle = length × breadth

=> 8 × 5

=> 40 m²

____________________________

» Number of tile = $\frac{Total\:area\:of\: rectangular\:room}{Area\: of \:tiles\: square}$

=> $\dfrac{40}{0.25}$

=> $\dfrac{40\:\times\:100}{25}$

=> $\dfrac{8\:\times\:100}{5}$

=> $8\:\times\:20$

=> 160 tiles

_____________________________

160 tiles required to cover the floor of the room.
