Question

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

Answer 1

3s

Explanation:

In an equilateral triangle all the three sides are equal.

Perimeter is the sum of line forming the boundary of any geometric shape.

Here in the case of triangle, the perimeter would be equal to sum of its three sides.

Perimeter = s + s + s

= 3s

Thus perimeter of equilateral triangle would be 3s, given s is one of its side length.

Answer 2

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.
