the area of the equilateral triangle is 27.71 square centimeters.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the formula for the area of an equilateral triangle is A = sqrt(3) / 4 * S^2, where S is the side of the equilateral triangle.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this formula becomes 27.71 = sqrt(3) / 4 * S^2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for S to get S = sqrt(27.71 * 4 / sqrt(3)) = 7.99959398.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that's the length of one side of the triangle.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the perimeter of the triangle is 3 times that = 23.99878194.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that's the length of the wire that was used to shape the triangle.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the length of the rectangle is 9.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the formula for the perimeter of the rectangle is 2 * (L + W) = 23.99878194.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "divide both sides of that equation by 2 to get L + W = 23.99878194 / 2 = 11.99939097.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "since L = 9, W must be equal to 11.99939097 minus 9 = 2.999390969.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you have:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "L = 9
\n" ); document.write( "W = 2.999390969\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the area of the rectangle is equal to L * W = 9 * 2.999390969 = 26.99451872 square centimeters.\r
\n" ); document.write( "
