Area of Equilateral Triangle A= S2 * (Root 3)/4, where A= Area of the triangle S= Side of the triangle.
If the sides are different lengths it ain't equilateral...
A triangle has area, not volume.
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.
Perimeter of equilateral triangle: 24 units Area of equilateral triangle: 27.713 square units rounded to three decimal places
Area = 1443.376 cm2
Area = 0.5*base*altitude
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.
In our example, the area of the equilateral triangle is 1/6 of the area of the regular hexagon
