P=2L+2W
\n" ); document.write( "W=L-2
\n" ); document.write( "84=2L+2(L-2)
\n" ); document.write( "84=2L+2L-4
\n" ); document.write( "4L=84+4
\n" ); document.write( "4L=88
\n" ); document.write( "L=88/4
\n" ); document.write( "L=22 METERS IS THE LENGTH.
\n" ); document.write( "W=22-2=20 METERS IS THE WIDTH.
\n" ); document.write( "PROOF:
\n" ); document.write( "84=2*22+2*20
\n" ); document.write( "84=44+40
\n" ); document.write( "84=84
