Question

The side of equilateral triangle is 4.5 CM. find it's perimeter.
​

Answer 1

Answer:

The side of an equilateral triangle us 4.5cm

So,

Perimeter is Sum of all the sides

4.5+4.5+4.5

=>13.5cm

Answer 2

Answer:

Hence, value of perimeter of equilateral triangle will be 13.5 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 = 4.5 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,

$Perimeter = 3 \times sides = 3 \times 4.5 = 13.5\:cm$
