Question

The perimeter of an equilateral triangle is $16.5cm$. Find the length of its side. $\left(incm\right)$

Answer 1

The perimeter of an equilateral triangle is $16.5cm$
Let the side of the triangle be $xcm$.
Since all sides of the equilateral triangle are the same.
Hence, $3x=16.5$
$x=5.5cm$
Hence, side of the triangle is $5.5cm$
