$\blue{\mapsto \: length \: of \: tile = 8cm} \\ \blue{\mapsto \: breadth \: of \: tile = 4cm}$

___________________

$\blue{ \mapsto \: length \: of \: floor = 8m} \\ \blue{\mapsto \: breadth \: of \: floor = 4m}$

$\star\small\fbox{find - }</p><p>$

$\green{ \longmapsto \: how \: many \: tiles \: will \: be \: required \: to \: cover \: the \: floor \: ?}$

$\pink{\star\small\fbox{solution - }}</p><p>$

$\red{\dagger \: area \: of \: tile = l \times b }\\ \red{= 8 \times 4 = {32 \: cm}^{2} } \\ \red{\dagger \: area \: of \: floor = l \times b} \\ = \red{8 \times 4 = {32 \: m}^{2} }$

$\circ \: as \: we \: know \: that \: - \: 1 \: m = 100 \: cm$

$\color{gold}\longmapsto \: {32 \: m}^{2} = {3200 \: cm}^{2}$

$\orange{\therefore \: tiles \: required = \frac{3200 \: {cm}^{2} }{ {32 \: cm}^{2} } = 100}$
