Answer:
5 square units.
Step-by-step explanation:
See the attached graph where D, E, F, and G points are plotted.
So, in trapezium DEFG, the parallel sides are GF and DE.
Now, it is clear from the graph that, the length of segment GF = (3 - 1) = 2 units and the length of line segment DE = (3 - 0) = 3 units.
Now, the altitude of the trapezium is GD with length (4 - 2) = 2 units.
Therefore, the area of the trapezium will be given by
[tex]A = \frac{1}{2} \times (GF + DE) \times GD[/tex]
⇒ [tex]A = \frac{1}{2} \times (3 + 2) \times 2 = 5[/tex] square units. (Answer)
