I think his -4 because the E represents 2.5
Split the figure into 3 shapes: a trapezoid,a rectangle and a triangle
Area of trapezoid
A= 1/2(b1+b2) h
A = 1/2(3 +9)(8)
A = 1/2(12)(8)
A = 48 square units
Area of rectangle:
A = L x W
A = 9 x 8
A = 72 square units
Area of triangle
A = 1/2bh
A = 1/2(3)(8)
A = 12 square units
Area of figure = 48 square units + 72 square units + 12 square units
= 132 square units
Answer
132 square units
Based on the statement of your question that A lies on the line of reflection of it means the reflected A is also in the line of reflection, in that reason alone i conclude that C. point A' lies on the line of reflection but not on point A its because A' is also reflected from A.

Step-by-step explanation:
Let's set Huilan's age to h and Thomas's age to t.
Since Huilan is 13 years younger than Thomas, we can write:
The sum of both their ages is 41, so let's combine the variables h and t together.
We said that h = t - 13, so substitute this value into the equation.
Combine like terms.
Add 13 to both sides of the equation.
Divide both sides of the equation by 2.
Thomas's age is 27 years old.
