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 determined the perimeter of equilateral triangle.

As per question,

We have,

Side of equilateral triangle = 4.5 cm

As we know that,

Equilateral triangle is that particular triangle whose all sides are equal.

As we know that,

Perimeter of any figure can be determined by adding the length of outer borders of the figure.

So, perimeter of equilateral triangle will be $3 \times sides$

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

Thus we will get it as,

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