Attached is a picture showing the plot in the plane.
Note that for a complex number , x + iy.
The real part of the number is put on the x axis and the imaginary part is put on the y axis.
So plotting:
A = 4 + 1i
B = 9 + 7i
C = 5 + 8i
See picture.

Answer:
D. 135.37 in²
Step-by-step explanation:
We have that the gift paper consists of two circles and a square.
Thus, we will need to find the area of the circles and the square.
Now, as the diameter of the circle = 4 inches
So, the radius of the circle = = 2 inches
Since, the area of a circle =
This implies that area of the two circles =
i.e. Area of the circles =
i.e. Area of the circles =
i.e. Area of the two circles = 25.133 in²
Further, one side of the square = 10.5 inches
Thus, the area of the square =
i.e. Area of the square =
i.e. Area of the square = 110.25 in²
So, the overall area of the gift paper = 25.133 + 110.25 = 135.37 in².
Hence, the amount of paper used by Angela is 135.37 in².
