\n" ); document.write( "Hi,
\n" ); document.write( "Note: As to the Area of a rectangle: A = l*w
\n" ); document.write( "let w be the width. Then (w+8cm) would be the length
\n" ); document.write( "\"w%28w+%2B+8%29=+180%5Ecm\"
\n" ); document.write( "\"w%5E2+%2B+8w+=+180%5Ecm\"
\n" ); document.write( "\"w%5E2+%2B+8w+-+180%5Ecm+=+0\"
\n" ); document.write( "(w +18)(w - 10) = 0
\n" ); document.write( "w = -18 cannot use this value for w
\n" ); document.write( "w = 10cm and l = 18cm
\n" ); document.write( "check your answer
\n" ); document.write( "10cm*19cm = 180cm^2 \n" ); document.write( "
\n" );
