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.
A triangle with side a: 3, side b: 3, and side c: 3 units has an area of 3.9 square units.

27+27+27=81 The equation for the perimeter an equilateral triangle is "side + side + side". And since it is an equilateral all the sides are the same length.
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))

Area = 15.58846 cm2
Area of an equilateral triangle is s*(sqrt 3)/2, where s is the length of a side, or: area = s * 0.866666. . .
Side length is about 12 units (11.99963) given an area of 62.35
389.711 ft2
15.2 inches.

0.4330 times the length of a side (in square units of length)
The side length is 15.2 (15.19671) inches.
The side length is 18.24 (18.23606) inches.
-- 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).
The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
