It is: 0.5*length squared*(sin 60 degrees)
The formula for the perimeter of an equilateral triangle is P = 3s, where P is the perimeter and s is the length of one side. The formula for the area of an equilateral triangle is A = (s^2 * sqrt(3)) / 4, where A is the area and s is the length of one side.
An equilateral triangle
a equilateral triangle has all the sides the same length.
All three sides of an equilateral triangle are..."equal" in length.
An isoceles triangle has TWO sides of equal length but an equilateral triangle has THREE sides of equal length
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.

-- The area of any triangle is 1/2 (length of the base x height). -- For an equilateral triangle, that's equivalent to 1/2 x sqrt(3) x (length of a side).
