Algebra.Com's Answer #462068 by Cromlix(4381)![]() ![]() You can put this solution on YOUR website! If a equilateral triangle has a perimeter of \n" ); document.write( "36 then it has 3 sides of 12ins each. \n" ); document.write( "area of a triangle = 1/2(b*h) \n" ); document.write( "The height will be found by creating a \n" ); document.write( "line from the mid point of one of the \n" ); document.write( "equilateral's sides up to the opposite \n" ); document.write( "vertex of the triangle. \n" ); document.write( "A right angled triangle is formed with \n" ); document.write( "a side of 6ins. (1/2 base) and a hypotenuse \n" ); document.write( "of 12ins. \n" ); document.write( "12^2 - 6^2 = height^2 \n" ); document.write( "144 - 36 = height^2 \n" ); document.write( " height = square root of 108 \n" ); document.write( " height = 10.4ins. \n" ); document.write( "Area of equilateral = 1/2(6*10.4) \n" ); document.write( " = 31.2 ins^2 \n" ); document.write( "Area of regular hexagon = 3 root3/2 * x^2 (x = side) \n" ); document.write( " 31.2 = 3 root 3/2 * x^2 \n" ); document.write( " 31.2/2.598 = x^2 \n" ); document.write( " 12 = x^2 \n" ); document.write( " x = root 12 \n" ); document.write( " x = 3.5ins. \n" ); document.write( "Hope this helps. \n" ); document.write( ":-) \n" ); document.write( " |
