Check the picture below.
since the figure has two pairs of parallel sides, tis a parallelogram.
the area of a parallelogram is just base * height, in this case, the base is 12, and its height is "y" which is 7, so the area will just be
12 * 7.
now, the perimeter, well, we know what "z" is, so the perimeter will just be 12 + 7√2 + 12 + 7√2, or
24 + 14√2.
It should be 7/2, also you might wanna say please.. :l
Answer:
A. (2(4x+7x))=P
B. 2(4(3)+7(3))=2(12+21)=2(33)=66
Step-by-step explanation:

Answer:
The letter C
Step-by-step explanation:
North china plain runs along near the northern east border. It's territory has a noticeable river going through it, and is close to the Gulf of Jilin. A is most likely not correct, since North china plane doesn't go up that high the Yellow river. So it is safe to assume the answer is most likely C
