Question

perimeter of equilateral triangle A is 99 cm find the side of triangle

Answer 1

Answer:

Hence, value of side of equilateral triangle having perimeter 99 cm will be $Side = \frac{Perimeter}{3} = \frac{99}{3}=33\:cm$

Step-by-step explanation:

In context to question asked,

We have to determine the side of the equilateral triangle.

As per question,

We have,

Perimeter of equilateral triangle = 99 cm

As we know that,

Equilateral triangle is that type of triangle whose all sides are equal.

Perimeter is nothing but the sum of length of outer borders of the triangle.

So, for determining the perimeter of equilateral triangle,

We will add all the outer faces of the triangle.

So, we will use the formula $Perimeter = 3 \times sides$ for determining the perimeter of triangle.

So, for determining the side of triangle, we will put the value of perimeter of equilateral triangle in above formula and divide it by 3.

Thus we will get,

$Side = \frac{Perimeter}{3} = \frac{99}{3}=33\:cm$
