Question

If a side of an equilateral triangle is $xcm$, then its perimeter will be :

• A. $x$
• B. $2x$
• C. $3x$
• D. $4x$

Answer 1

The correct option is C

$3x$

Since its an equilateral triangle, so its all sides will remain same as $xcm$.

Perimeter = Sum of all three sides

$$\begin{gathered} =x+x+x \\ =3xcm \end{gathered}$$
