For an equilateral triangle, When you draw the perpendicular angle bisector, you will obtain a 30 -60 -90 triangle with one of the sides as the hypotenuse, which is s
\n" ); document.write( "The height, opposite the 60 degree angle, is s* $\"sqrt%283%29\"$ /2.
\n" ); document.write( "Therefore f(x) = x* $\"sqrt%283%29\"$ /2.
\n" ); document.write( "So, it follows f(3) = 3* $\"sqrt%283%29\"$ /2. This will be the height with a side of 3.
