Answer 2

Answer:

The answer is $3\sqrt 2$ cm

Step-by-step explanation:

Given side length of the equilateral triangle is $\sqrt{2}$ cm

And since we know that all the sides in equilateral triangles are equation

Therefore the required perimeter $=3\times$ side length $=3\times \sqrt 2=3\sqrt 2$ cm

(Since triangle has three sides)
