Question

the floor of a rectangular room measure 16m by 11m the floor has to be tiled with square tiles of length 40 cm find the num of tiles required

Answer 1

We know that,

$area \: of \: rectangle = length \: \times bredth$
A = 16 × 11
$a \: = 176 {cm}^{2}$

$area \: of \: square \: = {side}^{2}$
area of square tile is 16m

Number of tiles = Rectangular area ÷ Square area
= 176 ÷ 16
= 11

Therefore 11 tiles is required to fill the rectangular space.

Answer 2

$\tt ฏGIVEN:−$

$\tt length \: of \: floor = 4m =400cm$

$\tt breadth\: of \: floor= 3m = 300cm$

$\tt length\: of \: single \: tile= 8cm$

$\tt breadth\: of \: single \: tile= 6cm$

$\tt ฏFIND:-$

$\tt no. \: of \: tiles \: reqire = ?$

$\tt ฏSOLUTION:-$

$\tt area \: of \: floor = 400 \times 30 \\ \tt = 120000 {cm}^{2}$

$\tt area \: of \: each \: tile= 8 \times 6 = 4 {cm}^{2}$

$\tt now \: let \: no. \: of \: tiles = x$

$\tt = > area \: of \:hall= x\times area \: of \: each$

$\tt = > 120000 = x(48)$

$\tt = > x = \frac{ \cancel{ 120000}}{ \cancel{48}} = 2500$

$\boxed{ \tt so \: total \: no. \: of \: tile \: is \boxed{2500}}$
