P=2L+2W
\n" ); document.write( "80=2*28+2W
\n" ); document.write( "80=56+2W
\n" ); document.write( "2W=80-56
\n" ); document.write( "2W=24
\n" ); document.write( "W=24/2
\n" ); document.write( "W=12 ANS. PROOF:
\n" ); document.write( "80=2*28+2*12
\n" ); document.write( "80=56+24
\n" ); document.write( "80=80
