There is only one basic shape for an equilateral triangle. The area can only vary as the length of the sides vary.
In our example, the area of the equilateral triangle is 1/6 of the area of the regular hexagon
225(radical "3")/4
The area is: 15.6 (15.58846) square inches.
60 because there are 3 sides in a triangle and 60 x 3 =180, triangles are always equal to 180 * * * * * The above "answer" has nothing to do with the question! The area of an equilateral triangle with sides of s cm is s*sqrt(3)/4 square cm.
