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

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=12or 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,
