An equilateral triangle the real formula use in calculating it

Calculating what?

google is your friend. just search for equilateral triangle.

If the side is s, then

perimeter = 3s
area = √3/4 s^2

To calculate various properties of an equilateral triangle, you can use the following formulas:

1. Perimeter (P): The perimeter is the sum of the lengths of all three sides of the equilateral triangle.
Formula: P = 3s
Where 's' is the length of one side of the triangle.

2. Area (A): The area is the amount of space enclosed by the equilateral triangle.
Formula: A = (sqrt(3) / 4) * s^2
Where 's' is the length of one side of the triangle.

3. Height (h): The height is the perpendicular distance from any vertex of the triangle to the opposite side.
Formula: h = (sqrt(3) / 2) * s
Where 's' is the length of one side of the triangle.

4. Interior Angle (θ): The interior angle is the angle formed inside the equilateral triangle at each vertex.
Formula: θ = 60 degrees

5. Exterior Angle (α): The exterior angle is the angle formed by extending one side of the equilateral triangle.
Formula: α = 360 degrees / 3 = 120 degrees

By plugging in the value of one side 's' into these formulas, you can calculate the perimeter, area, height, and the angles of the equilateral triangle.
