Correct Answer: 3 square units
Solution : The area of a triangle formed by a line and the coordinate axes $=\frac{1}{2} \times \text{base} \times \text{height}$ The line $3x + 2y = 6$ At $y = 0⇒x = \frac{6}{3} = 2$ At $x = 0⇒y = \frac{6}{2} = 3$ So, the base and the height of the triangle are $2$ units and $3$ units respectively. $\text{Area of the triangle formed} = \frac{1}{2} \times 2 \times 3 = 3$ Hence, the correct answer is 3 square units.
