Answer:
The expression which is equivalent to the length of one side of the equilateral triangle is:
[tex]\dfrac{1}{3}p[/tex]
Step-by-step explanation:
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:
[tex]x+x+x=p\\\\i.e.\\\\3x=p\\\\i.e.\\\\x=\dfrac{p}{3}[/tex]
which is equivalent to:
[tex]\dfrac{1}{3}p[/tex]
