The area of a triangle with vertices at (0, −2) ,(8, −2) and (9, 1) is 12 square units
Solution:
Given, vertices of the triangle are A(0, -2), B(8, -2) and C(9, 1).
We have to find the area of the given triangle.
The area of triangle when vertices are given is:


Here in our problem,

Now, substitute the above values in the formula:


Hence, the area of the triangle is 12 square units.
