Let the 3 vertices of the triangle be 3 points. Each point is an ordered pair. Write the 3 points as rows of a 3x3 matrix with each point being a row and the third entry in each row is 1. For example if one vertex was located at (1,2) The row of the matrix would be 1 2 1
Do the same with all the vertices.
Then take 1/2 the determinant of that matrix and that is the area. If it is a negative number, then take the positive value. It will be negative or positive depending on the order of the rows, but area is always positive.
By using trigonometry
The answer will depend on the shape of the triangle and what is known about it.
By using sides we get area of triangle and then using (1/2)heightxbase we get height.
