Question

find the perimeter of an equilateral triangle of side 13.8 metre

Answer 1

Hi !!




Side of equilateral triangle = 13.8 m




Therefore,

Perimeter of equilateral triangle = 3 × ( Side ) = 3 × 13.8 = 41.4 m

Answer 2

Answer:

Hence, perimeter of equilateral triangle will be 41.4 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 equilateral triangle = 13.8 cm

As we know that,

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

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

As, we have,

Formula for determining the perimeter of equilateral triangle as,

$Perimeter = 3 \times sides$

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

Thus we will get,

$Perimeter = 3 \times sides = 3 \times 13.8 = 41.4 \:cm$
