The Himalayan region covers $1,050,000$ km${}^2$, the Western Ghats region covers $200,000$ km${}^2$, and the Thar Desert covers $200,000$ km${}^2$. What percentage of the Indian mainland ($3,287,263$ km${}^2$) is covered by these three regions combined? Round to one decimal place.

Step-by-step solution

1. Add the areas of the three regions: $1,050,000+200,000+200,000=1,450,000$ km${}^2$.
2. Divide the combined area by the total mainland area: $1,450,000÷3,287,263\approx 0.4413$.
3. Multiply by 100 to convert to percentage: $0.4413\times 100=44.13$%.
4. Round to one decimal place → 44.1%.
