You can put this solution on YOUR website!
Perimeter = 2*length + 2*width
\n" ); document.write( "Perimeter = 2*(x + 40) + 2x
\n" ); document.write( "200yds = 2x + 80 + 2x
\n" ); document.write( " 4x + 80 = 200
\n" ); document.write( " 4x = 200 - 80
\n" ); document.write( " 4x = 120
\n" ); document.write( " x = 30.
\n" ); document.write( "Length = 70yds
\n" ); document.write( "Width = 30yds
\n" ); document.write( "Perimeter = 2*length + 2*width
\n" ); document.write( " = 2*70 + 2*30
\n" ); document.write( " = 200yds.
