Question

A piece of wire is $750cm$long . What will be the length of each side if the wire is used to form an equilateral triangle .

Answer 1

Finding the length of side of equilateral triangle:

Perimeter of equilateral triangle $=3\times side$

$750=3\times side$

$$\begin{gathered} side=\frac{750}{3} \\ side=250cm \end{gathered}$$

Hence, the length of each side of equilateral triangle is$250cm$
