That depends on what type of triangle is if the side given is equal to the perimeter divided by 3 then it is an equilateral triangle.
You cannot. For a given area, an equilateral triangle will have the smallest perimeter but that perimeter can be increased - without limit - without increasing the area.

A scalene triangle is a triangle in which all three sides have different lengths. The difference between a scalene right triangle and a scalene obtuse triangle is that in the first one, we can find the measure length of the third side when we know the lengths of the two other sides, and in the second one we cannot.
It is: perimeter minus hypotenus+base = height Area = 0.5*base*height
