Question

Find the perimeter of an equilateral triangle whose side is 6.5cm

Answer 1

Answer:

19.5cm

Step-by-step explanation:

perimeter of equalateral triangle=sum of all sides.

therefore 6.5×3=19.5

Answer 2

Answer:

Hence, value of perimeter of equilateral triangle will be 19.5 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 = 6.5 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,

$Perimeter = 3 \times sides = 3 \times 6.5 = 19.5\:cm$
