L*W=AREA.
\n" ); document.write( "L=X
\n" ); document.write( "W=X-3
\n" ); document.write( "X*(X-3)=40
\n" ); document.write( "X^2-3X-40=0
\n" ); document.write( "(X-8)(X+5)=0
\n" ); document.write( "X-8=0
\n" ); document.write( "X=8 ANS. FOR THE LENGTH.
\n" ); document.write( "W=8-3=5 ANS. FOR THE WIDTH.
\n" ); document.write( "PROOF:
\n" ); document.write( "8*5=40
\n" ); document.write( "40=40
