Let $\"x\"$ - the width
\n" ); document.write( "Then $\"4x\"$ - the length
\n" ); document.write( "The perimeter of a rectangular is $\"P=2%28w%2Bl%29\"$ , where $\"w\"$ is the width, $\"l\"$ is the length of a rectangular
\n" ); document.write( "The equation
\n" ); document.write( " $\"70=2%28x%2B4x%29\"$
\n" ); document.write( " $\"2%2A5x=70\"$
\n" ); document.write( " $\"10x=70\"$
\n" ); document.write( " $\"x=7\"$ meters is the width of a rectangular
\n" ); document.write( " $\"4x=4%2A7=28\"$ meters is the length of a rectangular \n" ); document.write( "

\n" );
