Question

The side of an equilateral triangle is shown by $\mathrm{I}$. Express the perimeter of the equilateral triangle using $\mathrm{I}$.

Answer 1

Side of an equilateral triangle $=\mathrm{I}$

We know that perimeter of a traingle is given by $=$ sum of all sides

Perimeter $=\mathrm{I}+\mathrm{I}+\mathrm{I}$

$=3\mathrm{I}$

Hence, the perimeter of given triangle is $=3\mathrm{I}$
