# The side of an equilateral triangle is shown by $ l $. Express the perimeter of the equilateral triangle using $ l $.

Given:

The side of an equilateral triangle is shown by $l$.

To do:

We have to express the perimeter of the equilateral triangle using \( l \).

Solution:

We know that,

The perimeter of a triangle is equal to the sum of the lengths of the sides.

The sides of an equilateral triangle are equal in length.

Therefore,

Perimeter of the given triangle $=l+l+l=3l$.

The perimeter of the given triangle in terms of $l$ is $3l$.
