atroni [7]

Answer:

100:9

Therefore:

10 : 3 ⇒ (10)² : (9)²

100 : 9 is the ratio of the areas.

Flauer [41]

You have to write this based on yourself. Just answer each question one by one and then you can compare a whole paragraph.

So for each question you have to choose what you believe you are.

Which social class do you belong to; lower, middle, or upper class?

Why? This could be because you're well off or because you don't have that much money, it depends on which class you believe you are.

Who are your peers? Peers refers to people within the same age bracket as you.

In your everyday choices, whom do you tend to take as a reference point? This is basically asking who influences you, for example your mother or your brother, who do you use as your guidance for how you act. The remaining questions are just asking to specify who, your peers or family members, it's just an addition to the main question.

Step-by-step explanation:

Hope this helps:)
