Question

The area of the $△ABC$ as shown in the diagram above is.

• A. $\frac{1}{2}\times a\times c$ sq. unit
• B. $\frac{1}{2}\times (a+d)\times c$ sq. unit
• C. $\frac{1}{2}\times b\times c$ sq. unit

Answer 1

The correct option is A $\frac{1}{2}\times a\times c$ sq. unit

To calculate the area of the $\Delta ABC$ as shown in the diagram.
We need a base and it's corresponding height.
Now, for the height as $c$, the corresponding base is $AB$.
$\therefore$ Area $ABC=\frac{1}{2}\times c\times a$ sq. unit
