Answer:
Area of an ellipse(a), ,having x and y being the lengths of the largest and smallest diameters of the ellipse = π xy
The lengths of the largest and smallest diameters of the ellipse is called Major Axis and Minor axis of the ellipse.
[tex]\rightarrow a=\pi x y\\\\\rightarrow y=\frac{a}{\pi \times x}[/tex]
