$\rm \large \purple {Solution \: 1 : }$

• $\rm \pink {Regular \: Shapes : } shapes \: which \: have \: equal \: angles \: and \: equal \: sides. \\\rm \pink {e.g} : square , \: equilateral \: triangle.$

• $\rm \pink {Irregular \: Shapes :} \: shapes \: which \:do \: not \: have \: equal \: sides \: and \: equal \: angles. \\\rm \pink {e.g} : rectangle , \: isosceles \: triangle.$

• $\rm \pink {Perimeter :} (boundary) \: is \: the \: sum \: of \: all \: the \: sides \: of \: a \: plane \:figure.$

$\rm \large \purple {Solution \: 2 : }$

$\rm \pink {Length \: of \: lid} = 40 \: cm \\\rm \pink {breadth \: of \: lid} = 10 \: cm$

$\rm \pink{ Perimeter \: of \: tape } = l \: + \: b \: + \: l \: + \: b \\\rm = 40 + 10 + 40 + 10 \\\rm = 100 \: cm$

$\rm \pink {Required \: length \: of \: tape \: is = 100cm }$

$\rm \large \purple {Hence \: Verified :) }$
