You need to add the problem you need help with....
Answer:
D. (–3, –6) and (5, 10)
Step-by-step explanation:
The system has equations:
...(1)
and
...(2)
Equate both equations;

Rewrite in standard form:

We factor to obtain:

By the zero product principle;


When x=-3, y=2(-3)=-6
This yields the ordered pair (-3,-6).
When x=5, y=2(5)=10
This yields the ordered pair (5,10).
The correct choice is D.
I am pretty sure that it would be 20 sq. inches( if not correct, check on the internet and you will probably get the correct answer.)
It is given in the question that

And 
can also be written as

Therefore,


That gives,
