Question

how many square tiles of side 14 cm will be required to pave the floor of a rectangular room of 9.8 m ×6.4 m

Answer 1

Firstly we find the area I.e.
9.8*6.4=62.72-------1
then we will find the area of the tile I.e.
14*14=296----------2
now we will devide eq. 1 and 2
(62.72/296)
4.71938

Answer 2

Answer:

Step-by-step explanation:

firslty,

area of the floor = 9.8 m ×6.4 m

                                 = 62.72 m ²

now,

area of the tile= 14cm ×14cm

let us convert to m

100cm = 1m

14cm = 0.14m

=>0.14 × 0.14

= 0.0196 cm²

now tiles required = are of floor/area of tile

= 62.72/0.0196

= 3200 tiles
