\n" ); document.write( "W=X
\n" ); document.write( "2(X+12)+2X=100
\n" ); document.write( "2X+24+2X=100
\n" ); document.write( "4X=100-24
\n" ); document.write( "4X=76
\n" ); document.write( "X=76/4
\n" ); document.write( "X=19 FT IS THE WIDTH.
\n" ); document.write( "19+12=31 FOR THE LENGTH.
\n" ); document.write( "PROOF:
