Let x=width and y=length\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since the \"length of a rectangle is 3 in. more than the width\", this means that \"y=x%2B3\". Also, because the \"perimeter of the rectangle is 24 in\", this tells us that \"P=24\" \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"P=2x%2B2y\" Start with the formula for the perimeter of a rectangle\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"24=2x%2B2%28x%2B3%29\" Plug in \"P=24\" and \"y=x%2B3\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"24=2x%2B2x%2B6\" Distribute\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"24-6=2x%2B2x\" Subtract 6 from both sides.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"18=4x\" Combine like terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"18%2F4=x\" Divide both sides by 4.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x=9%2F2\" Reduce.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the first part of the answer is \"x=9%2F2\" or \"x=4.5\". This means that the width is 4.5 inches.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y=x%2B3\" Go back to the first equation\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y=9%2F2%2B3\" Plug in \"x=9%2F2\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y=15%2F2\" Combine the fractions.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the second part of the answer is \"y=15%2F2\" or \"y=7.5\". This means that the length is 7.5 inches.\r
\n" ); document.write( "

\n" ); document.write( "\n" ); document.write( "Answer:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the width is 4.5 inches and the length is 7.5 inches
