W=H+2
\n" ); document.write( "V=LWH
\n" ); document.write( "105=7(H+2)H
\n" ); document.write( "105=7(H^2+2H)
\n" ); document.write( "105=7H^2+14H
\n" ); document.write( "7H^2+14H-105=0
\n" ); document.write( "7(H^2+2H-15)=0
\n" ); document.write( "7(H+5)(H-3)=0
\n" ); document.write( "H-3=0
\n" ); document.write( "H=3 ANS. FOR THE HEIGHT.
\n" ); document.write( "W=3+2=5 ANS FOR THE WIDTH.
\n" ); document.write( "PROOF:
