let one side =a
\n" ); document.write( "let other side =b
\n" ); document.write( "perimeter=2(a+b)
\n" ); document.write( "2(a+b)=8(given)
\n" ); document.write( "a+b=8/2=4
\n" ); document.write( "so b=4-a
\n" ); document.write( "area = a*b
\n" ); document.write( "area=a*(4-a)
\n" ); document.write( "area=4-a^2
\n" ); document.write( "this is equal to 3 sq km
\n" ); document.write( "4-a^2=3
\n" ); document.write( "4-3=a^2
\n" ); document.write( "1=a^2
\n" ); document.write( "a=1
\n" ); document.write( "b=4-a
\n" ); document.write( "b=4-1=3
\n" ); document.write( "the dimns are 3km and 1 km
\n" ); document.write( "good day
\n" ); document.write( "
\n" );
