Let l be the length,w be the width. \n" ); document.write( "w - l = 6 (given)-------------(1) \n" ); document.write( "perimeter = 30 \n" ); document.write( "=> 2(l+w) = 30 => l + w = 30/2 =15------(2) \n" ); document.write( "Solving (1) & (2) \n" ); document.write( "w-l=6 \n" ); document.write( "w+l=15 \n" ); document.write( "=> 2w =21 =>w=21/2=10.5m \n" ); document.write( "l= 4.5m \n" ); document.write( " |
