Question

Find the perimeter of equilateral triangle of side 3 ½ cm​

Answer 1

Answer:

The perimeter of the equilateral triangle is 10 cm...

Answer 2

Answer:

Hence, value of perimeter of equilateral triangle will be 10.5 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 = $3\frac{1}{2}\:cm = 3.5\:cm$

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,

$Perimeter = 3 \times sides = 3 \times 3.5 = 10.5\:cm$
