The perimeter of rectangle is 2(l+b) where l is the length and b is the width\r
\n" ); document.write( "\n" ); document.write( "2(l+b) = 38
\n" ); document.write( "2(7.5 + b) = 38
\n" ); document.write( "15 + 2b = 38
\n" ); document.write( "2b = 38 - 15
\n" ); document.write( "2b = 23
\n" ); document.write( "b = 11.5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Width is 11.5cm \n" ); document.write( "
