Question

The perimeter of an equilateral triangle is $20.1cm$. Find the sides of the equilateral triangle.

Answer 1

Given the perimeter of the equilateral triangle is $20.1$ cm.

Let the side of the equilateral triangle be $a$ cm.

Then by the problem,

$3a=20.1$

or, $a=6.7$

So the sides of the equilateral triangle are of length $6.7$ cm each.
