Question

The perimeter of a equilateral triangle is 6/7
m. What is the length of its each side?
​

Answer 1

Answer:

2/7

Step-by-step explanation:

Perimeter =3 × side

Given 3s=6/7

S=2/7

Answer 2

An equilateral triangle is a triangle in which all three sides are equal.

Let the sides of an equilateral be a .

Perimeter of a triangle=a+a+a=3a

Perimeter=6/7 m

$∴ \: \: \: \: \: 3a = \frac{6}{7} m \\ \: \: \: \: \: \: \: \: \: \: \: a = \frac{6}{7} m \times \frac{1}{3 } = \frac{2}{7} m$

Therefore, the length of each side= 2/7 m
