Equilateral Triangle Area Calculator
With our calculator you do not have to try to remember or calculate the formula used to find the area. Simply input the area of a side and our calculator will do the rest. If you want to know the formula used to calculate the area of an equilateral triangle it is (√3/4)(A)^2 where A is the length of one side. As stated earlier the standard formula for the area of a triangle can be used to find the area of an equilateral triangle, but this formula cannot work for other triangles that are not equilateral.
