$7.198 * 10^6

Step-by-step explanation:

Given that :

Total Area of Alaska = 5.9 * 10^5 mi²

Cost of Alaska per square mile = $12.20

Total amount paid to purchase Alaska:

(Total area in square miles * Cost per square mile)

(5.9 × 10^5) * $12.20

(5.9*12.20) * 10^5

71.98 * 10^5 dollars

= $7.198 * 10^6

Hence, amount the United States paid Russia for the purchase of Alaska is approximately $7.198 * 10^6
