Question

Perimeter of equilateral triangle having side 28cm

Answer 1

hey mate here is your answer..

perimeter =sum of 3 sides

sides are 28 ,28 and 28

because sides of equilateral∆ are equal..

perimter=28+28+28

p=84

so perimeter is 84cm

Answer 2

Answer:

Hence, value of perimeter of equilateral triangle will be 84 cm

Step-by-step explanation:

In context to question asked,

We have to determined the perimeter of equilateral triangle.

As per question,

We have,

Side of equilateral triangle = 28 cm

As we know that,

Equilateral triangle is that particular triangle whose all sides are equal.

As we know that,

Perimeter of any figure can be determined by adding the length of outer borders of the figure.

So, perimeter of equilateral triangle will be $3 \times sides$

So, for determining the perimeter of the equilateral triangle we will put the value of side of equilateral triangle in above formula,

Thus we will get it as,

$Perimeter = 3 \times 28=84\:cm$
