If the total area of the Indian mainland is $3,287,263{\text{km}}^2$ and the area of the Himalayan region (including Jammu & Kashmir, Himachal Pradesh, Uttarakhand, Sikkim, Arunachal Pradesh, and Assam) is $1,050,000{\text{km}}^2$, what percentage of the mainland area is covered by the Himalayan region? Round your answer to one decimal place.

Step-by-step solution

1. Write the formula for percentage: $(\text{part}/\text{whole})\times 100$.
2. Substitute the given values: $(1,050,000/3,287,263)\times 100$.
3. Divide $1,050,000$ by $3,287,263$ to get approximately $0.3194$. Multiply by $100$ to convert to percentage: $0.3194\times 100=31.94$. Round to one decimal place: $31.9$%.
4. Thus the Himalayan region covers about 31.9% of the mainland area.
