let its width be x\r
\n" ); document.write( "\n" ); document.write( "so the length will then be x+3 (3inches greater)\r
\n" ); document.write( "\n" ); document.write( "The perimeter is then equal to
\n" ); document.write( "x+x+(x+3)+(x+3)\r
\n" ); document.write( "\n" ); document.write( "this is equal to 24
\n" ); document.write( "x+x+(x+3)+(x+3)=24
\n" ); document.write( "4x+6=24
\n" ); document.write( "4x+6-6=24-6 (subtracting 6 from both sides of the equation)
\n" ); document.write( "4x=18
\n" ); document.write( "x=18/4
\n" ); document.write( "x=4.5\r
\n" ); document.write( "\n" ); document.write( "so the width is 4.5
\n" ); document.write( "the length will be 4.5+3=7.5\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
