Question

Find the area of ΔABC.Question options:A) 29.77B) 21.93C) 18.6D) 37.20

Answer 1

Given the figure of a triangle ABC

As shown:

$\begin{gathered} m\angle A=32\degree \\ AB=7.8 \\ AC=9 \end{gathered}$

The area (A) of the triangle will be calculated as follows:

$A=\frac{1}{2}\cdot AB\cdot AC\cdot\sin A$

substitute with the given values

$A=\frac{1}{2}\cdot7.8\cdot9\cdot\sin 32=18.6$

So, the answer will be option C) 18.6
