Step-by-step explanation:
ฏGIVEN:−
\tt length \: of \: floor = 4m =400cmlengthoffloor=4m=400cm
\tt breadth\: of \: floor= 3m = 300cmbreadthoffloor=3m=300cm
\tt length\: of \: single \: tile= 8cmlengthofsingletile=8cm
\tt breadth\: of \: single \: tile= 6cmbreadthofsingletile=6cm

\tt no. \: of \: tiles \: reqire = ?no.oftilesreqire=?
\tt ฏSOLUTION:-ฏSOLUTION:−
\begin{gathered}\tt area \: of \: floor = 400 \times 30 \\ \tt = 120000 {cm}^{2}\end{gathered}
areaoffloor=400×30
=120000cm

\tt area \: of \: each \: tile= 8 \times 6 = 4 {cm}^{2}areaofeachtile=8×6=4cm

\tt now \: let \: no. \: of \: tiles = xnowletno.oftiles=x
\tt = > area \: of \:hall= x\times area \: of \: each=>areaofhall=x×areaofeach
\tt = > 120000 = x(48)=>120000=x(48)
