Answer 2

Answer:

Hence, side of equilateral triangle will be 24 cm

Step-by-step explanation:

In context to question asked,

We have to determine the side of equilateral triangle.

As per question,

We have,

Perimeter of equilateral triangle = 72 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 side of triangle, we will put the value of perimeter of triangle in above formula.

Thus we will get,

$Side = \frac{perimeter}{3}\\=>Side = \frac{72}{3} = 24\:cm$
