If A is the length of one side, the area will be (√3/4)A2
An equilateral triangle has three equal angles, and the sum of the angles in any triangle is always 180 degrees. Therefore, each angle in an equilateral triangle measures 60 degrees.
Area of an equilateral triangle is s*(sqrt 3)/2, where s is the length of a side, or: area = s * 0.866666. . .
Area of Equilateral Triangle A= S2 * (Root 3)/4, where A= Area of the triangle S= Side of the triangle.
Perimeter of equilateral triangle: 24 units Area of equilateral triangle: 27.713 square units rounded to three decimal places
Find the area of an equilateral triangle if its perimeter is 18 ft
Area = 0.5*base*altitude
In our example, the area of the equilateral triangle is 1/6 of the area of the regular hexagon
If an equilateral triangle and a square have equal perimeters, then the ratio of the area of the triangle to the area of the square is 1:3.

There is only one basic shape for an equilateral triangle. The area can only vary as the length of the sides vary.
To find the surface area of an equilateral triangular prism you take the area of the rectangular sides and the triangular bases and add them up and your done.
