Answer:
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
Answer:
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,
