Answer:
   34 square units
Step-by-step explanation:
The figure can be considered to be a trapezoid with a rectangle removed.
The area of the trapezoid is ...
   A = (1/2)(b1 +b2)h
   A = (1/2)(10 +6)(5) = 40
The area of the rectangle is ...
   A = LW
   A = (3)(2) = 6
Then the area of the shaded portion of the figure is ...
   shaded area = trapezoid area - rectangle area
   = 40 - 6 = 34 . . . square units
 
        
             
        
        
        
Answer:
Rigid transformations are ways to move an object while not changing its shape or size. A  
translation (slide) moves . object vertically. horizontally or both. A reflection (flip) moves an object across a line of reflection as in a mirror. A rotation (tum) moves an object clockwise or  
object across a line of reflection as in a mirror. A rotation (tum) moves an object clockwise or  
counterclockwise around s point.

Answer:
A) Reflection.
Step-by-step explanation:
From the figure shown, we can see that the blue triangle is flipped about the x-axis to form the red triangle.
When an object is flipped about a line, then this transformation is called reflection about that line.
Thus, we can say that reflection is taking place in the figure shown in which the x-axis is acting like a mirror. The blue triangle is the pre-image and the red triangle is the image after reflection. 
The reflection about x-axis is given by:
 
 
We can check the co-ordinates of the triangles and confirm the the transformation occurring
Points of pre-image triangle:

Points of image triangle

Thus, the transformation is reflection.
