Let the length and width of the rectangle be l and w units
\n" ); document.write( "Given,
\n" ); document.write( "l/w = 3/2 => l = 3w/2
\n" ); document.write( "and (l + 15)/(w - 5) = 3/1 => l + 15 = 3w - 15
\n" ); document.write( "=> 3w = l + 30 = 3w/2 + 30
\n" ); document.write( "=> 3w/2 = 30
\n" ); document.write( "=> w = 20
\n" ); document.write( "=> l = (3x20)/2 = 30
\n" ); document.write( "Hence, the length and breadth of the rectangle are 30 and 20 units
\n" ); document.write( "
\n" );
