Answer 2

$Let \: a , b \:and \: c \:are \: sides \:of \\equilateral \: triangles$

$\boxed { \pink { Perimeter \:of \:an \: equilateral \:triangle = 3\times side }}$

$i) Perimeter \: of \: first \: triangle\\ = 3\times 1 \\= 3 \: cm \: --(1)$

$ii) Perimeter \: of \: second\: triangle\\ = 3\times 2\\= 6 \: cm \: --(2)$

$iii) Perimeter \: of \: third \: triangle\\ = 3\times 3\\= 9 \: cm \: --(3)$

$From \: (1), (2) \:and \: (3) , we \:get$

$\red{ Sequence \:on \: the \: perimeter \: of} \\\red{the\: equilateral \:triangles } \green {= 1,6,9 }$
