L=LENGTH
\n" ); document.write( "DIAGONAL=(L+10)
\n" ); document.write( "W=50
\n" ); document.write( "USING THE PYTHAGOREON THEROUM A^2+B^2=C^2
\n" ); document.write( "L^2+50^2=(L+10)^2
\n" ); document.write( "L^2+2500=L^2+20L+100
\n" ); document.write( "20L=2500-100
\n" ); document.write( "20L=2400
\n" ); document.write( "L=2400/20
\n" ); document.write( "L=120 IS THE LENGTH.
\n" ); document.write( "120+10=130 IS THE DIAGONAL.
\n" ); document.write( "PROOF
\n" ); document.write( "120^2+50^2=130^2
\n" ); document.write( "14400+2500=16900
\n" ); document.write( "16900=16900
