Question

what is the number of square tiles with side 2m required to cover the floor of a rectangular room with length 10m and breadth 40m​

Answer 1

Answer:

100 tiles

Step-by-step explanation:

length of rectangular room =40 m

breadth of rectangular room = 10 m

area of rectangular room = 10 m × 40 m

= 400 m²

side of 1 tile = 2 m

area of tile = 2m × 2m

= 4m²

IN 4 M² = 1 TILE

IN 400 M² = (1÷4)× 400

= 100 tiles

Answer 2

So first let's find the area of the room's floor :

area (i) = l × b

        = 10 × 40

        = 400 $m^{2}$

Now find area of tile :

area (ii) = s × s

            = 2 × 2

            = 4 $m^{2}$

So the no. of tiles needed is :

400 ÷ 4 = 100 tiles

Therefore 100 tiles are needed to cover the floor
