You can put this solution on YOUR website!
W = x
\n" ); document.write( "L = 2W\r
\n" ); document.write( "\n" ); document.write( "P = 2w + 4w = 90 *This is the equation you are looking for.
\n" ); document.write( "6w = 90
\n" ); document.write( "w = 15 cm
\n" ); document.write( "l = 30 cm\r
\n" ); document.write( "\n" ); document.write( "2(15) = 30
\n" ); document.write( "2(30) = 60
\n" ); document.write( "30 + 60 = 90 cm
\n" ); document.write( "This does check,
