length = 4 times width
\n" ); document.write( " l = 4 b
\n" ); document.write( "perimeter of the pool = 140
\n" ); document.write( " but perimeter of the rectangle = 2(l+b)
\n" ); document.write( " so 2(l+b)= 140
\n" ); document.write( " l+b = 70
\n" ); document.write( " put l= 4b
\n" ); document.write( " 4b+b= 70
\n" ); document.write( " 5b =70
\n" ); document.write( " b= 14
\n" ); document.write( " l= 4*14
\n" ); document.write( " =56
\n" ); document.write( " so length = 56 m
\n" ); document.write( " width = 14 m
\n" ); document.write( "
\n" ); document.write( "
\n" );
