Question

What will be the area of the traingle as shown in figure?

• A. $\frac{ab}{2}$
• B. $\frac{ac}{2}$
• C. $\frac{bc}{2}$
• D. $ab$

Answer 1

The correct option is A $\frac{ab}{2}$

Given,
Base of triangle$=BC=a$
Height of triangle$=AD=b$
Let's consider a triangle $\Delta ABC$ as shown.
Here $BC=a$ and $AD=b$
As we know,
Area of$△ABC=\frac{1}{2}\times \text{Base}\times \text{Height}$
$\Rightarrow \frac{1}{2}\times a\times b=\frac{ab}{2}$
