$For \: fencing \: the \: lawn \: we \: should \: take \: the \: perimeter \: of \: the \: lawn.$

$Perimeter \: of \: square \: lawn = 4 \times \: side$

$= 4 \times 18 \: cm$

$= 72 \: m$

$So, \: 72 \: m \: wire \: will \: be \: needed \: to \: fence \: the \: lawn.$

$Cost \: of \: fencing \: one \: metre = Rs \: 2$

$Therefore, \: the \: cost \: of \: fencing \: 72 \: m \: = 72 \times Rs \: 2$

$= Rs \: 144$

$Total \: cost \: of \: fencing \: the \: lawn \: is \: Rs \: 144.$
