Question

How many tiles whose length and breadth are $10cm$ and $6cm$ respectively will be needed to fit in a rectangular region whose length and breadth are $80cm$ and $30cm$ respectively $?$

Answer 1

STEP $1:$ Find the area of tile

$\Rightarrow$ Area of tile $=length\times breadth$

$=10cm\times 6cm$

$=60cm$

STEP $2:$ Find the area of rectangular region

$\Rightarrow$ Area of rectangular region $=80cm\times 30cm$

$=2400cm$

STEP $3:$ Number of tiles required

$\Rightarrow$Number of tiles required $=\frac{Areaofrec\tan gularregion}{Areaoftile}$

$=\frac{{\displaystyle 2400}}{60}$

$=40$

Therefore, the number of tiles needed is $40.$
