Question

In Fig., the area of triangle ABC (in sq.units) is:

• A. 15
• B. 10
• C. 7.5
• D. 2.5

Answer 1

The correct option is C

7.5

Construction : Draw $AM\perp BC.$
It can be observed from the given figure that BC = 5 unit and AM = 3 unit
It $\Delta ABC,BC$ is the base and AM is the height.
Area of triangle $ABC=\frac{1}{2}\times base\times height$
$\frac{1}{2}\times BC\times AM$
$\frac{1}{2}\times 5\times 3sq.units$
$7.5sq.units$
The correct answer is 7.5 which is given by option C.
