\"D=sqrt%28L%5E2%2BW%5E2%29\" Start with the formula for the diagonal of a rectangle.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"D=sqrt%28%2869%29%5E2%2B%2828%29%5E2%29\" Plug in \"L=69\" and \"W=28\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"D=sqrt%284761%2B%2828%29%5E2%29\" Square \"69\" to get \"4761\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"D=sqrt%284761%2B784%29\" Square \"28\" to get \"784\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"D=sqrt%285545%29\" Add \"4761\" to \"784\" to get \"5545\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"D=74.4647567645259\" Take the square root of \"5545\" to get \"74.4647567645259\" (this value is approximate).\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"D=74.5\" Round to the nearest tenth.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So a rectangle with a length of \"69\" inches and a width of \"28\" inches has a diagonal length of about \"74.5\" inches.
\n" ); document.write( "
