Answer:
1High concentration of electronegative/electropositive elements available in the atmosphere/environment (to allow basic chemical reactions that life may need: on earth, life adapted for oxygen);
1High concentration of electronegative/electropositive elements available in the atmosphere/environment (to allow basic chemical reactions that life may need: on earth, life adapted for oxygen);2Low and stable income of radiation (because radiation disrupts complex molecules much faster than life could or would bear);
1High concentration of electronegative/electropositive elements available in the atmosphere/environment (to allow basic chemical reactions that life may need: on earth, life adapted for oxygen);2Low and stable income of radiation (because radiation disrupts complex molecules much faster than life could or would bear);3Enough distance from the sun so as to not be highly influenced by solar flares (also because of radiation). Though red dwarves last for much longer than K-type stars such as our sun, it’s debatable if earth-like lifeforms would be able to live in a red dwarf system, because the habitable zone around that kind of star is simply too close and the planet would suffer a lot in the early ages with solar flares, let alone keep an atmosphere;

Answer:
Question:-
Find the length of a side of an equilateral triangle perimeter is 72 cm.
Given :-
Figure is equilateral triangle
Perimeter of figure = 72cm
Aim :-
To find side of the triangle
Equilateral triangle:-
In a equilateral triangle, all the sides are equal
All angles are equal.
Hence, Perimeter = Side + side + side => 3 × side
Let the side be x cm.
As we know that,
3 × side = Perimeter,
substituting the values,
3 × x = 72
Transposing 3 to the RHS (Right hand side),
x = \dfrac{72}{3}x=
3
72
By reducing to the lowest terms,
x = 24
Side of the triangle = 24cm
