How do you find the area of an equilateral triangle?


Answer by  Senbagam (138)

In an equilateral triangle all the sides are equal and all the angles at all sides are equal. So it's area can be calculated as half multiplication of height and width.

In general you find the area of a triangle with the formula A=(1/2)bh, that is the area is one half the length of the base times the length of the height. For a equilateral triangle, the height can be found in terms of the length of the sides. This allows us to get the formula A=(s^2 sqrt(3))/4.
