Question

Find the side of equilateral triangle whose perimeter is $0.639m$.

Answer 1

Finding the side of equilateral triangle :

Given, perimeter of equilateral triangle $=$$0.639m$

We know that, perimeter of equilateral triangle is $3\times side$

Therefore,

$\begin{array}{rcl}3\times side& =& 0.639m\\ side& =& \frac{0.639}{3}\\ side& =& 0.213m\end{array}$

Therefore, side of equilateral triangle is $0.213m$.
