An equilateral triangle has a perimeter p . the length of one side is p/3 . which exprecion is equivalent to the length of one side
3p
2\3p
1/3p
3/4p

The expression which is equivalent to the length of one side of the equilateral triangle is:

Since we are given the Perimeter of the equilateral triangle as: P

We know that Perimeter is the sum of all the sides of a triangle.

Also, the triangle is a equilateral triangle this means that the sum of the length of all the sides of a triangle is equal to p

Let the length of one side be x

i.e. we have:

which is equivalent to:
