Question

The perimeter of an equilateral triangle is 17.7cm find the length of each side of the triangle

Answer 1

Answer:

The length of each side of the triangle is 5.9cm

Step-by-step explanation:

In a equilateral triangle the length of each side is equal.

Let, one side be x

We know that, the perimeter of a equilateral triangle is sum of its three sides

ATQ, x+x+x=17.7

or,3x=17.7

or, x=5.9

The length of each side of the triangle is 5.9cm

Answer 2

Answer:

Hence, value of length of side of equilateral triangle will be 5.9 cm

Step-by-step explanation:

In context to question asked,

We have to determine the length of side of equilateral triangle.

As per question,

We have,

Perimeter of triangle = 17.7 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 length of side of equilateral triangle,

We will put the value of perimeter of triangle given in the question in above formula,

Thus we will get,

$Side = \frac{Perimeter}{3}\\=>Side = \frac{17.7}{3} = 5.9\:cm$
