we know AB=CD
\n" ); document.write( "AC=BD= $\"sqrt%285%29\"$
\n" ); document.write( "perimeter= $\"2AC%2B2AB\"$
\n" ); document.write( "let $\"AB\"$ = $\"x\"$ then $\"AD\"$ = $\"2x\"$
\n" ); document.write( "you have right angle triangle
\n" ); document.write( " $\"sqrt%285%29%5E2\"$ + $\"x%5E2\"$ = $\"%282x%29%5E2\"$
\n" ); document.write( " $\"x\"$ = $\"sqrt%285%2F3%29\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"p\"$ = $\"2%2Asqrt%285%29%2B2%2A%28sqrt%285%2F3%29%29\"$ \n" ); document.write( "
