$\tt\it\bf\it\large\bm{\mathcal{\fcolorbox{blue}{white}{\green{Solution:-}}}}$

_____________________________

Area of tiles ➨12x5➨60cm²

Area of rectangular

region➨70x36➨2520cm²

{ Area of tiles x Total no.of tiles ➨Area

of rectangular region }

•°• 60 x Total no.of Tiles ➨ 2520

➠ Total no.of Tiles ➨ 2520/60

➠Total no.of Tiles ➨ 42

$\tt{\red{Hence,\:Total\:no.of\:tiles}}$

$\tt{\red{ \;\;\;\;= 42\:(Answer ) }}$
