Question

The perimeter of an equilateral triangle is 162m. Find the length of
a side.

Answer 1

Answer:

The perimeter of an equilateral triangle is 15.5 cm

Let the side of the triangle be x cm.

Since all sides of the equilateral triangle are the same.

Hence, 3x=16.5

x=5.5cm

Hence, side of the triangle is 5.5 cm

Answer 2

Answer:

Hence, value of length of side of equilateral triangle will be 54 m

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 = 162 m

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,

$Side = \frac{Perimeter}{3}\\=>Side = \frac{162}{3} = 54\:m$
