Answer: The correct option is (B) 4 square units.
Step-by-step explanation: We are given to find the area of the triangle LMN shown in the figure.
From the triangle, we note that
LN is the base and PM is the height of the triangle LMN, and
LN = 4 units and PM = 2 units.
The AREA of a triangle with base b units and height h units is given by
[tex]Area=\dfrac{1}{2}\times b\times h.[/tex]
Therefore, the AREA of triangle LMN will be
[tex]A_{LMN}=\dfrac{1}{2}\times LN\times PM=\dfrac{1}{2}\times4\times2=4~\textup{sq. units}.[/tex]
Thus, the required area of triangle LMN is 4 square units.
Option (B) is CORRECT.
