Question

Find the perimeter of an equilateral triangle if each of its side measures is $12s.$

Answer 1

It is given that each side measures of equilateral triangle is $12s.$

Let $a=12s$

Perimeter of an equilateral triangle $=3\times a,$where $\text{'}a\text{'}$ is the side of an equilateral triangle$.$

Perimeter of an equilateral triangle $=3\times 12s$

$=36s$

Hence$,$ the perimeter of an equilateral triangle is $36s$.
