Question

What is the area of the obtuse triangle below?

Answer 1

Answer:

C. 99 sq.units

Step-by-step explanation:

Area of triangle =

$\frac{1}{2} \times b \times h$

( where, b = base and h = height )

so, area =

=》

$\frac{1}{2} \times 22 \times 9$

=》

$11 \times 9$

=》

$99$

hence, area = 99 sq. units

Answer 2

Given:

The figured of an obtuse triangle.

To find:

The area of the triangle.

Solution:

We know that, the area of a triangle is

$Area=\dfrac{1}{2}\times Base\times height$

From the given figure it is clear that the height of the triangle is 9 and the base is 22. So, the area of the triangle is

$Area=\dfrac{1}{2}\times 22\times 9$

$Area=11\times 9$

$Area=99$

The area of the given triangle is 99 sq. units.

Therefore, the correct option is C.
