1. $\"L=5W\"$ Length is 5 times the width.
\n" ); document.write( "2. $\"2L%2B2W=70\"$ The perimeter of the rectangle is 70.
\n" ); document.write( " $\"2%285W%29%2B2W=70\"$ Substitute Eq. 1 into Eq. 2 and solve for W.
\n" ); document.write( " $\"10W%2B2W=70\"$
\n" ); document.write( " $\"12W=70\"$
\n" ); document.write( " $\"W=70%2F12=35%2F6\"$
\n" ); document.write( " $\"W=5.83\"$
\n" ); document.write( " $\"L=5W=5%285.83%29=29.17\"$
\n" ); document.write( "L=29.17 cm
\n" ); document.write( "W=5.83 cm
\n" ); document.write( " \n" ); document.write( "
