is the filament of 240v 1000w bulb thicker or thinner than the filament of 240v 100w bulb why

the resistance of 1st bulb =240×240/1000 ohom
=57.6 ohom
and the second bulb's resistance=240×240/100 ohom
=576 ohom
So, the 1st filament will be thicker because as we know that R is proportional to 1/A where A is area of filament.
