Question

what is the area of $\triangle abc$ if $h = 12$ and $ac = 5$?

(options: 120, 30, 15, 60)

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 result

$\frac{1}{2} \times 60 = 15$

Answer:

15
