$\huge \sf{ \underline{ \underline{Question:-}}}$

How many square tiles of side 14 cm will be required to pave the floor measuring

$\huge \sf{ \red{ \underline{ \underline{Solution:-}}}}$

$Area \: of \: square \: tiles=(14×14)=196cm²$

Measurement of floor =4.3m×7m

1m=100cm

So 4.3m=430cm

7m=700cm

$\bold{ Area \: of \: floor \: =(430×700)=301000cm²}$

$\bold{Number \: of \: tiles \: required= \frac{301000}{196} {cm}^{2} }$

=1535.71
