Answer:

Step-by-step explanation:
The area of a trapezoid is given by the average of the bases multiplied by the height.
What we're given:
- Height of 3
- Bases of 1 and 4
The average of the bases 1 and 4 is equal to 
Therefore, the area of the trapezoid is 
F(-1)= 4*7(-1) = 4*-7 = -28
F(2)= 4*7(2) = 4*14 = 56

Step-by-step explanation:
the translation < 3, 2 >
means add 3 to the original x- coordinate and add 2 to the original y- coordinate, then
A (3, 0 ) → A' (3 + 3, 0 + 2 ) → A' (6, 2 )
B (4, - 2 ) → B' (4 + 3, - 2 + 2 ) → B' (7, 0 )
C (1, - 3 ) → C' (1 + 3, - 3 + 2 ) → C' (4, - 1 )
