How do I determine the area of a star if I have the peak wavelength and temperature of the star?

I used Wein's Law to determine the temperature of a star since I have the peak wavelength but i need to determine luminosity and area. How will I go about this?



Peak Wavelength- 300

Temperature- 9667KHow do I determine the area of a star if I have the peak wavelength and temperature of the star?You don't . All you have is surface temperature. Since you don't have either luminosity or size, you can't determine either. With temperature, given luminosity, you could find size; given size, you could determine luminosity.
