here... diameter of circle= diagonal of rectangle.
\n" ); document.write( "so,
\n" ); document.write( "diameter= 2*10= 20cm.
\n" ); document.write( "so, diagonal of rectangle= 20cm.
\n" ); document.write( "(diagonal)^2 = length^2 + width^2
\n" ); document.write( "so,
\n" ); document.write( "20^2 = 16^2 +w^2
\n" ); document.write( "144= w^2
\n" ); document.write( "w=12 cm.
\n" ); document.write( "so,
\n" ); document.write( "area of rectangle = length* width = 16*12 = 192 cm^2.
\n" ); document.write( "
\n" );
