Question

The area of a rectangular floor of a room is 320 square metre how many square tiles of Side 2 cm are required to cover the floor?​

Answer 1

Step-by-step explanation:

in this question we have the area of the floor which is 320m^2

area of single tile is 2*2 =4

so no of tiles is 320/4

now the answer will be 80

Answer 2

$\huge\bold\blue{Question}$

The area of a rectangle floor of a room is 320 square metre how many square tiles of Side 2 cm are required to cover the floor?

$\huge\bold\red{\underline{\underline{Answer:}}}$

$\bold{800000 \ tiles \ are \ required \ to \ cover \ the \ floor}$

$\huge\bold\blue{Explanation}$

Area of tile × Number of tiles

=Area of rectangular floor

i.e.

Number of tiles=Area of rectangular floor÷Area of tile

$\huge\bold\orange{Given:}$

$\bold{Area \ of \ rectangular \ floor=320m^{2}}$

$\bold{Side \ of \ square \ shaped \ tile=2cm}$

$\huge\bold\pink{To \ find:}$

$\bold{Number \ of \ tiles \ require \ to \ cover \ floor}$

$\huge\bold\green{\underline{\underline{Solution}}}$

$\bold{1m=100cm}$

$\bold{1cm=\frac{1m}{100}}$

$\bold{2cm=\frac{2m}{100}}$

Hence,side of a squared shape tile=0.02m

$\bold{Area \ of \ tile=}$=0.0004$\bold{m^{2}}$

Number of tiles required=

Area of rectangular floor÷Area of tile

(Multiply numenator and denominator by 10000)

$\bold{=\frac{3200000}{4}}$

$\bold{=800000}$

$\huge\bold\red{Verification}$

$\bold{Area \ of \ tile ×number \ of \ tiles}$

=0.0004×800000

=$\bold{360m^{2}}$

=$\bold{Area \ of \ rectangular \ floor}$

Therefore,

$\bold\purple{800000 \ square \ tiles \ are \ required.}$
