L= 3W-10
\n" ); document.write( "perimeter of the rectangle:
\n" ); document.write( "2L+2W Substitute in this formula the value for L given in the problem:
\n" ); document.write( "2(3W-10)+2W ≥ 180
\n" ); document.write( "6W-20+2W ≥ 180 Add W on left and add 20 on both sides:
\n" ); document.write( "8W ≥ 200
\n" ); document.write( "W ≥ 25 is the width. And the length is:
\n" ); document.write( "3(25)-10= 75-10= 65 is the length \n" ); document.write( "

\n" );
