Explanation:

Step1: Find British colony area

From the table, Britain's colonial area = $12,740,000$ sq. miles

Step2: Calculate Triple Entente total area

Triple Entente = Britain + France + Russia
Area = $12,740,000 + 4,400,000 + 0 = 17,140,000$ sq. miles

Step3: Calculate Germany-Austria-Hungary area

Area = $1,139,000 + 0 = 1,139,000$ sq. miles

Step4: Explain colonial population economic benefits

1. Labor: Colonial populations offer low-wage workers for overseas plantations/mines, reducing production costs for the mother country.
2. Market: Colonial populations create a guaranteed market for the mother country's finished goods, boosting domestic manufacturing revenue.
3. Raw Materials: Colonial populations can be employed to extract local raw materials (e.g., cotton, rubber) for the mother country's industrial production, ensuring a steady, low-cost supply chain.

Answer:

1. 12,740,000 square miles
2. 17,140,000 square miles
3. 1,139,000 square miles
4. (For question 3 at the bottom of the left column): A large colonial population can provide cheap labor for the mother country's industries, serve as a captive market for the mother country's manufactured goods, and supply raw materials at low costs to support the mother country's production.
