Find the area of rectangle whose length is 4.7 an and breadth is 2 cm.

If the area of the ellipse ((x^(2))/(a^(2)))+((y^(2))/(b^(2)))=1 is 4 pi, then find the maximum area of rectangle inscribed in the ellipse.

The ellipse E_(1):(x^(2))/(9)+(y^(2))/(4)=1 is inscribed in a rectangle R whose sides are parallel to the coordinates axes. Another ellipse E_(2) passing through the point (0, 4) circumscribes the rectangle R. The length (in units) of the major axis of ellipse E_(2) is
