# Equilateral Triangle Area Calculator

Use our equilateral triangle area calculator to find the area of an equilateral triangle when you know the length of a side. The formula used here is specific to equilateral triangles where all 3 sides and all 3 angles are the same. The traditional triangle area formula of A=1/2 B*H can still be used but if you do not have that information then a more complicated formula can be used to find the area of an equilateral triangle with the length of one side.

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.
