So perimeter of equilateral triangle = a + a + a = 3.a The area of an equilateral triangle can be calculated using the formula, Area = 3 4) × a … Triangles are assumed to be two-dimensional plane figures, unless the context provides otherwise (see Non-planar triangles, below). In rigorous treatments, a triangle is therefore called a 2-simplex (see also Polytope). Elementary facts about triangles were presented by Euclid, in books 1–4 of his Elements, written around 300 BC.
