Answer 2

Answer:

The side of an equilateral triangle is 10 cm .

Step-by-step explanation:

Given information,

Perimeter of equilateral triangle is 30cm.

We have to find out the side of an equilateral triangle.

Equilateral triangle means the triangle which is having all equal sides.

By finding the length of one side we can find out the length all sides.

As we know that,

The perimeter of equilateral triangle = 3S

Where,

S is the side of an equilateral triangle.

By putting given values in the formula

30 = 3 S

$S = \frac{30}{3}$

S = 10

Hence,

The side of an equilateral triangle is 10 cm .
