Answer 1

$\rm\large{\underline{\underline\color{darkblue}{Given:-}}}$

$\rm\dashrightarrow{Length =3.75cm}$

$\rm\dashrightarrow{Breadth = 2.4 cm}$

$\rm\large{\underline{\underline\color{darkblue}{Find:-}}}</p><p></p><p>Find the number of tiles.</p><p></p><p>[tex]\rm\large{\underline{\underline\color{darkblue}{Solution:-}}}[\tex]</p><p></p><p></p><p>[tex]\sf\hookrightarrow{Area \: of \: stage = 3.75 × 2.4}\\ </p><p>=7000 \\ = 7 { \rm{m}}^{2}$

$\sf\hookrightarrow \: Area \: of \: the \: tiles= = \frac{50 \times {10}^{ - 2m} }{l} \times \frac{15 \times {10}^{ - 2} }{b} \\ = 300 \\ = 900 \times {10}^{ - 4} \\ = \frac{7}{9 \times {10}^{2} }$

$\sf\hookrightarrow \: Number \: of tiles = \frac{7}{9 \times {10}^{2} } \\ \purple {= \frac{700}{9} }$

$\bf\mapsto{Number \: of \: tiles = \frac{700}{9}. }$

$\rule{259mm}{1mm}$

Answer 2

Answer:

length= 3.75m,breath= 2.4m

area of stage =3.75m×2.4m (when we convert it into cm)

= 375cm×240cm

area of tiles= 60cm×15cm

so, no. of tiles= area of stage/area of a tile

= 375×240cm²/ 60cm×15cm

=25×4

=100 tiles needed
