What is the area of the obtuse triangle given below

Option D 9 sq units

Step-by-step explanation:

we know that

The area of a triangle is equal to

where

b is the base

h is the height

In this problem we have

substitute in the formula

D. 9 sq. units.

Step-by-step explanation:

We know that , the area of a triangle =

In the given picture , it can be seen that the height of the triangle = 2 units

and base length of triangle = 9 units

Then, the area of a triangle =

i.e. Area of a triangle = 9 square units.

Hence, the correct answer is option D. 9 sq. units.

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
