Given, Area A = 50w-w&2
\n" ); document.write( "Differentiating withrespect to w, we get
\n" ); document.write( "dA/dw= 50-2w
\n" ); document.write( "For maximum or minimum value of A,
\n" ); document.write( "dA/dw=0
\n" ); document.write( "50-2w=0
\n" ); document.write( "50=2w
\n" ); document.write( "50/2=w
\n" ); document.write( "w=25
\n" ); document.write( "
\n" );
