See carefully how the length of one rectangle is given and the width of the other similar rectangle is given. \r
\n" ); document.write( "\n" ); document.write( "First rectangle: \"2%2A9%2B2%2Aw=30\"
\n" ); document.write( "\"9%2Bw=15\"
\n" ); document.write( "\"w=15-9=6\"
\n" ); document.write( "Dimensions: Length 9, Width 6.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Similar rectangle is of width 3, therefore, since distance dimensions are in proportion 3/6=1/2, the length is \"9%2F2=highlight%284%261%2F2%29\".
\n" ); document.write( "Dimensions: length \"4%261%2F2\", width 3.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Perimeter of this similar rectangle is \"2%2A4.5%2B2%2A3=highlight%2815%29\". Done.
\n" ); document.write( "
\n" );
