What is the area of a triangle with vertices at (0, −2), (8, −2) , and (9, 1) ? Enter your answer in the box. units²

The area of a triangle is A=1/2*b*h

When we graph the vertices of the triangle on a graph, we see that the lowest points are at y=-2, and the highest point is at y=1.  Therefore, our height is 3.

The base of the triangle goes from (0,-2) to (8,-2), which gives us a length of 8 for our base.

A=1/2*(8)*(3)

A=12

or

12 square unit.

Step-by-step explanation:

Since, the area of a triangle having vertices ,  and  is,

Here, the vertices of the triangle are (0, −2), (8, −2) and (9, 1),

Hence, area of the given triangle is,

answer: a.   one is a factor of every whole number since every number is divisible by itself.
