You can put this solution on YOUR website!
Perimeter P = 2L + 2W = 80. We also have
\n" ); document.write( "2W = L + 5 or
\n" ); document.write( "L = 2W - 5
\n" ); document.write( "Now substitute this onto the first equation...we get
\n" ); document.write( "2(2W - 5) + 2W = 80
\n" ); document.write( "4W - 10 + 2W = 80
\n" ); document.write( "6W - 10 = 80
\n" ); document.write( "6W = 90
\n" ); document.write( "W = 15 cm
\n" ); document.write( "L = 2(15) - 2 = 25 cm
\n" ); document.write( "
\n" );
