The area of triangle ABC is 18 square units

Step-by-step explanation:

From the image uploaded, the area of triangle ABC is calculated as follows;

$Area = \frac{1}{2} (base)\times (height)\\\\Area = \frac{1}{2} (|AB|)\times (|BC|)\\\\Area = \frac{1}{2} (6)(6)\\\\Area = 18 \ square \ units$

Thus, the area of triangle ABC is 18 square units
