Perimeter of equilateral triangle: 24 units Area of equilateral triangle: 27.713 square units rounded to three decimal places
Area of an equilateral triangle is s*(sqrt 3)/2, where s is the length of a side, or: area = s * 0.866666. . .
15.588 square inches.
A triangle with side a: 6, side b: 6, and side c: 6 inches has an area of 15.59 square inches.
A triangle with side a: 8, side b: 8, and side c: 8 yards has an area of 27.71 square yards.
It is: 3*20 = 60 cm
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.

To find the area of a regular hexagon with side length of 40cm, consider that since it is regular, then it consists of 6 equilateral triangles of side 40cm. Half of each of those triangles is a right triangle. By the pythagorean theorem, we know that if the hypotenuse is 40cm, and one side is 20cm, then the other side is the square root of (40cm squared - 20cm squared) or about 34.64cm. That makes the area of each of those 12 right triangle to be about 692.8cm, so the total area of the hexagon is about 8313.8cm.
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))
