Ответ:
c. 9 units²
Step-by-step explanation:
The formula for the area of a trapezoid is ...
A = (1/2)(b1 +b2)h
where b1 and b2 are the lengths of the parallel bases, and h is the height between them. From calculations using the coordinates, or from a figure, you can see that the base lengths area 3 units and 6 units, and the distance between them is 2 units.
Putting these numbers into the formula gives the area:
A = (1/2)(3 units + 6 units)(2 units) = 9 units²
