Given an altitude of 12 units, an equilateral triangle has side lengths of 13.9 (13.85641) units.
Area of Equilateral Triangle A= S2 * (Root 3)/4, where A= Area of the triangle S= Side of the triangle.

To get the area of an equilateral triangle, you just need to know the length of one side. Multiply the length of one side by the square root of three and then divide the product by four, and you will get the area of the triangle.
It is: 3*7 = 21cm

Area = 15.58846 cm2
Area = side^2 x (√3)/4
Area of an equilateral triangle is s*(sqrt 3)/2, where s is the length of a side, or: area = s * 0.866666. . .
A triangle with side a: 3, side b: 3, and side c: 3 units has an area of 3.9 square units.
You might want to give an area, it's impossible to answer your question as it is. The area of an equilateral triangle is [side2]*sqrt(3)/4, so reaarange: Side = 2*sqrt(area/sqrt(3))
