P=2L+2H
\n" ); document.write( "L=2H
\n" ); document.write( "54=2*2H+2H
\n" ); document.write( "54=4H+2H
\n" ); document.write( "54=6H
\n" ); document.write( "H=54/6
\n" ); document.write( "H=9 ANS. FOR THE HEIGHT.
\n" ); document.write( "L=2*9=18 ANS. FOR THE LENGTH.
\n" ); document.write( "PROOF:
\n" ); document.write( "54=2*18=2*9
\n" ); document.write( "54=36+18
\n" ); document.write( "54=54
\n" ); document.write( "AREA=LW
\n" ); document.write( "18*9=162 CM^2 IS THE AREA.
