EXPLANATION
The area of a triangle is calculated using the formula:
[tex]Area = \frac{1}{2} \times AB \times BC[/tex]
From the graph ,
AB=3--3=6 units.
BC=3--5=8 units
We substitute the values into the formula to get,
[tex]Area = \frac{1}{2} \times 6 \times 8 = 24sq. \: units[/tex]
The correct answer is B
