Answer: The correct option is (B) 24 square units.
Step-by-step explanation: We are given to find the area of the trapezium in the figure.
The AREA of a TRAPEZIUM with lengths of parallel sides as 'a' and 'b' units and height 'h' units is given by the formula:
[tex]A=\dfrac{1}{2}(a+b)h.[/tex]
In the given trapezium, we have
lengths of the parallel sides are
a = 4 units and b = 8 units,
and height, h = 4 units.
Therefore, the area of the given trapezium is
[tex]A\\\\\\=\dfrac{1}{2}(a+b)h\\\\\\=\dfrac{1}{2}\times(4+8)\times 4\\\\\\=12\times 2\\\\=24~\textup{sq. units.}[/tex]
Thus, the area of the trapezium is 24 square units.
Option (B) is correct.
