If an equilateral triangle has side length s, what is the total perimeter of the triangle? write an equation.

Given that there is an equilateral triangle.

We know that equilateral triangle has all sides equal.

Perimeter = sum of all sides

P = s+s+s = 3s

P = 3s is the equaiton where P = perimeter and s = side of the triangle.

In geometry, an equilateral triangle is a triangle in which all three sides and angles  are equal. ; that is, all three internal angles are also congruent to each other and hene have to be  each 60°. It is also a regular polygon, with three sides and so sometimes also referred to as a regular triangle.
