Let x = The Length of the Rectangle. Given the Width then
\n" ); document.write( "the equation relating Length, Width and Diagonal is
\n" ); document.write( " Width^2 + Length^2 = Diagonal^2
\n" ); document.write( " 21^2 + x^2 = 34^2
\n" ); document.write( " x^2 = 34^2 - 21^2
\n" ); document.write( " x^2 = 1156 - 441
\n" ); document.write( " x^2 = 715
\n" ); document.write( " x = 715^(1/2)
\n" ); document.write( " x = 26.7394
\n" ); document.write( " The Length of the Rectangle = 26.7394
\n" ); document.write( "
