Let the original length and breadth be l and b respectively . Hence initial area is lb
\n" ); document.write( "hence the new length is \"+l%281%2B20%2F100%29+\" = \"+l%28120%2F100%29\" = \"6l%2F5\"
\n" ); document.write( "hence new breadth will be \"+l%281-20%2F100%29\"=\"l%2880%2F100%29\"=\"4b%2F5\"
\n" ); document.write( "hence new area is \"6l%2F5%2A4l%2F5\"=\"24%2Alb%2F25\"
\n" ); document.write( "Hence the area decreases .
\n" ); document.write( "Decrease in area = \"lb-24lb%2F25\"=\"lb%2F25\"
\n" ); document.write( "hence % decrease =\"lb%2F25%2Flb%2A100\"=\"4+%25\" %
\n" ); document.write( "
\n" );
