Question

Compute the area of the triangle using the coordinates. What is the area of the triangle in square units? A. 10 B. 14 C. 7 D. 3.5

Answer 1

I don't see the triangle coordinates. Could you provide the three vertex coordinates (or the image)?

If you prefer the method: for vertices (x1,y1), (x2,y2), (x3,y3) the area is
Area = 1/2 | x1(y2−y3) + x2(y3−y1) + x3(y1−y2) |.
Provide the coordinates and I will compute the numeric answer.
