Correct Answer: 96 cm 2
Solution :
The given triangle with sides 16 cm, 12 cm, and 20 cm is a right-angled triangle. (since $20^2 = 16^2 + 12^2$)
The area of a right-angled triangle,
$\text{Area} =\frac{1}{2} \times \text{base} \times \text{height}$
⇒ $\text{Area} = \frac{1}{2} \times 16 \times 12 = \operatorname{ 96 cm^2 }$
Hence, the correct answer is 96 cm
