L=4W
\n" ); document.write( "AREA=LW
\n" ); document.write( "676=4W*W
\n" ); document.write( "676=4W^2
\n" ); document.write( "W^2=676/4
\n" ); document.write( "W^2=169
\n" ); document.write( "W=SQRT169
\n" ); document.write( "W=13 ANS FOR THE WIDTH.
\n" ); document.write( "L=4*13=52 ANS FOR THE LENGTH.
\n" ); document.write( "PROOF:
\n" ); document.write( "676=13*52
\n" ); document.write( "676=676
\n" ); document.write( "
