MCQ
In a $\triangle\text{ABC,}$ it is given that base $= 12\ cm$ and height $= 5\ cm$. Its area is:
- A$60\ cm^2$
- ✓$30\ cm^2$
- C$15\sqrt{3}\text{cm}^2$
- D$45\ cm^2$
✓
Answer
Correct option: B.
$30\ cm^2$
Area of triangle $=\frac{1}{2}\times\text{Base}\times\text{Height}$
Area of $\triangle\text{ABC}=\frac{1}{2}\times12\times5=30\text{cm}^2$
