Answer 2

Answer:

Hence, value of perimeter of equilateral triangle having side 1 cm will be $Perimeter = 3 \times 1 = 3\:cm$

Step-by-step explanation:

In context to question asked,

We have to determine the perimeter of the equilateral triangle.

As per question,

We have,

Side of equilateral triangle = 1 cm

As we know that,

Equilateral triangle is that type of triangle whose all sides are equal.

Perimeter is nothing but the sum of length of outer borders of the triangle.

So, for determining the perimeter of equilateral triangle,

We will add all the outer faces of the triangle.

So, we will use the formula $Perimeter = 3 \times sides$ for determining the perimeter of triangle.

So, for determining the perimeter of triangle, we will put the value of sides of equilateral triangle in above formula.

Thus we will get,

$Perimeter = 3 \times 1 = 3\:cm$
