L=W+7
\n" ); document.write( "P=2L+2W
\n" ); document.write( "210=2(W+7)+2W
\n" ); document.write( "210=2W+14+2W
\n" ); document.write( "210=4W+14
\n" ); document.write( "4W=210-14
\n" ); document.write( "4W=196
\n" ); document.write( "W=196/4
\n" ); document.write( "W=49 ANS. FOR THE WIDTH.
\n" ); document.write( "L=49+7=56 ANS. FOR THE LENGTH.
\n" ); document.write( "PROOF:
\n" ); document.write( "210=2*56+2*49
\n" ); document.write( "210=112+98
\n" ); document.write( "210=210
\n" ); document.write( "
