Since the semi circles are on the edge of the square and each side of square is h
\n" ); document.write( "this implies that the diameter of the semi circle is equal to h
\n" ); document.write( "but the radius is r
\n" ); document.write( "=> 2r = h...........equation(1)
\n" ); document.write( "Now area of square with side h is h^2 ( length * breadth)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Area of circle is pi*r^2
\n" ); document.write( "so area of semi circle will be half of it = 1/2(pi*r^2)
\n" ); document.write( "Area of 2 semi circles will be => 2*1/2(pi*r^2)
\n" ); document.write( "=> pi*r^2\r
\n" ); document.write( "\n" ); document.write( "So total area will be
\n" ); document.write( "h^2 + pi*r^2\r
\n" ); document.write( "\n" ); document.write( "But from equation (1) r = h/2
\n" ); document.write( "substituting in the above equation value of r
\n" ); document.write( "=> h^2 + pi*(h/2)^2
\n" ); document.write( "=> h^2 + pi*h^2/4
\n" ); document.write( "=> (4h^2 + pi*h^2)/4
\n" ); document.write( "=> h^2(4+pi)/4 \n" ); document.write( "
\n" );
