If the area of the Gangetic Plains is $1,200,000$ km${}^2$ and the total area of the Indian mainland is $3,287,263$ km${}^2$, what is the percentage of mainland area covered by the Gangetic Plains? Round to the nearest whole number.

Step-by-step solution

1. Write the formula for percentage: (part/whole)*100.
2. Divide the area of the Gangetic Plains by the total area: $1,200,000÷3,287,263\approx 0.365$.
3. Multiply by 100 to convert to percent: $0.365\times 100=36.5$%.
4. Round 36.5% to the nearest whole number → 37%.
