Question

Find the area of the triangle in the given figure.

Answer 1

From the figure-

We have to find the area of triangle $ABC$

So, we can see from the figure -

The height of the triangle $=3$ units

Its base, $BC=4-(-1)=5$ units
$\because Area=\frac{1}{2}\times base\times height$
$=\frac{1}{2}\times 3\times 5=7.5sq.units$
