An equilateral triangle has a side length of 30 meters. Determine the area of the triangle
\n" ); document.write( ".
\n" ); document.write( "Area of any triangle is (1/2)bh

\n" ); document.write( "calculating height:
\n" ); document.write( "let h = height
\n" ); document.write( "h^2 + 15^2 = 30^2
\n" ); document.write( "h^2 = 30^2 - 15^2
\n" ); document.write( "h^2 = 675
\n" ); document.write( "h = sqrt(675)
\n" ); document.write( "h = 25.981 meters
