Answer:
The correct option is B.
Step-by-step explanation:
The area of a triangle is
[tex]A=\frac{1}{2}bh[/tex]
where, b is base of the triangle and h is height of the triangle.
From the given figure it is clear that the base of the triangle is PR = 4 units and the height of the triangle is perpendicular distance of side PR from vertex Q, i.e., 3 units.
Substitute b=4 and h=3 in the above formula, to find the area of triangle PQR.
[tex]A=\frac{1}{2}\times 4\times 3[/tex]
On simplification we get.
[tex]A=6[/tex]
The area of triangle PQR is 6 square units. Therefore the correct option is B.
