Question

what is the area of $\triangle abc$ if $h = 12$ and $ac = 5$?
(options: 120, 60, 30, 15)

Explanation:

Step1: Recall triangle area formula

Area = $\frac{1}{2} \times \text{base} \times \text{height}$

Step2: Substitute given values

Base $AC=5$, height $h=12$.
Area = $\frac{1}{2} \times 5 \times 12$

Step3: Calculate the final value

$\frac{1}{2} \times 5 \times 12 = 30$

Answer:

30
