Question

find the perimeter of an equilateral triangle with side 6 cm​

Answer 1

Answer:

Hence the perimeter of equilateral triangle is 18 cm.

Step-by-step explanation:

According to the information provided in the question.

It is stated in the preceding question that,

The presented information is side of an equilateral triangle is 6 cm.

We need to find the perimeter of equilateral triangle.

The formula of perimeter of the equilateral triangle is as bellow,

$P=3a$

Where a is the side of the  equilateral triangle,

Substitute the value of side that is a = 9 we get,

$P=3\times 6\\P=18cm$

Hence the perimeter of equilateral triangle is 18 cm.

Answer 2

Answer:

Hence, value of perimeter of equilateral triangle will be 18 cm

Step-by-step explanation:

In context to question asked,

We have to determine the perimeter of equilateral triangle.

As per question,

We have,

Side of triangle = 6 cm

As we know that,

• All the sides of equilateral triangle are same.

• The perimeter of equilateral triangle can be determined by adding the length of all the sides.

As we have,

Formula for determining the perimeter of equilateral triangle as,

$Perimeter = side +side +side = 3 \times side$

So, for determining the value of perimeter of equilateral triangle,

We will put the value of length of triangle given in the question in above formula,

Thus we will get,

$Perimeter = 3 \times sides = 3 \times 6 = 18\:cm$
