You can put this solution on YOUR website!
you know ___ 2L + 2W = 124\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you are given ___ \"length is 6ft more than three times the width\" ___ L = 3W + 6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting ___ 2(3W + 6) + 2W = 124 ___ 8W + 12 = 124 ___ W = 14\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "plug the value for W into your original equation to find L
\n" ); document.write( "
\n" );
