You can put this solution on YOUR website!
The diagonal is the hypotenuse of right triangle using the given rectangle sides.
\n" ); document.write( "2:1, \"2%2F1=2x%2F1x\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%282x%29%5E2%2Bx%5E2=23%5E2\"
\n" ); document.write( "\"3x%5E2=23%5E2\"
\n" ); document.write( "\"x%5E2=%2823%2F3%29%5E2\"-----you could actually use this to finish the solution
\n" ); document.write( "\"x=sqrt%2823%29%2Fsqrt%283%29\"
\n" ); document.write( "\"x=sqrt%2869%29%2F3\", and you can say the other side length, \"2x=%282%2F3%29sqrt%2869%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Area of the rectangle is \"x%2A2x=2x%5E2=2%2A%2823%2F3%29%5E2=highlight%28529%2F9=58%267%2F9%29\"
