Explain the processes needed to raise the standard of living for the residents of
South Asia.

Human development and economic growth

Explanation:

The residents of Asia are known to be poor due to majority of them earning a low income. If the residents take more time to develop themselves and have solutions to some problems facing the region then that will mean more income and the standard of living will be raised also.

Economic growth is vital in every country's economy as a high economy growth will have a ripple effect and be advantageous to the citizens. They become more comfortable with more social amenities and low cost of living.

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
