Answer 2

$\huge \color{lime}{solution}$

Length of each side of water tank= 1.5m =150cm

As it is given that base is not covered with tiles so, five sides of the tank are covered with tiles.

$\sf \: therefore \\ \sf \:suurface \: area \: of \: water \: tank \\ = 5a \\ = 5(150) {}^{2} \\ = 112500cm {}^{2} \\ \sf \: side \: of \: tile = 25cm \\ \sf \: area \: of \: tile = {25}^{2} = 625cm {}^{2} \\ \sf \: number \: of \: to \: cover \: five \: sides \: of \: the \: tank \\ = \frac{112500}{625} \\ = 180 \\ now \\ \sf \: cost \: of \: one \: dozen \: tiles =rs.360 \\ \sf \: hence \: cost \: of \: \\ 180 = \frac{360}{12 } \times 180 \\ \implies \: rs.5400$
