Answer:
The perimeter of rectangle is 
Step-by-step explanation:
Let
x------> the length of rectangle
y----> the width of rectangle
we know that
The area of the constructed figure is equal to

so
-----> equation A
-----> equation B
substitute equation B in equation A

using a graphing calculator to resolve the quadratic equation
the solution is

Find the value of x

Find the perimeter of rectangle
The perimeter of rectangle is equal to

Starting weight: 5/6 lb. Of this, Jan used 1/5, which would be (1/5)(5/6) lb,
or 1/6 lb, leaving 4/6 lb, or 2/3 lb. unused.
2/3 lb
Now divide 2/3 lb by 8 portions: ----------------- = (2/24) lb/portion, or
8 portions
1/12 lb/portion.
0,-8 are the coordinates of the vertex.
Check all options:
A. The notion
represents the line YX. As you can see the line YX is present in the diagram.
B. Start with point Z, go to the point X and then to the point Y. You path is along ∠ZXY sides, this means that you can see ∠ZXY on the picture.
C. The notion
represents the ray ZX. On the picture is given segment ZX, not ray, then this option is false.
D. To form the ∠XYZ you have to connect points Z and Y. Without this connection ∠XYZ cannot be seen. This option is false.
Answer: True options are A and B.
