Answer:
The answer to your question is the letter D.About 22
Step-by-step explanation:
Data
China's area = 3 700000 mi²
Asia's area = 17 200000 mi²
Process
1.- Consider the Asia's area as 100% and use proportions to solve this problem
17 200000 -------------------------- 100 mi²
3 700000 -------------------------- x
x = (3700000 x 100) / 17200000
- Simplification
x = 370000000 / 17200000
-Result
x = 21.51 ≈ 22
