find the area of the triangle with vertices (-1 2 -1 2) (-1 2 -1 1) and (2 -1 2 2)
its 4 d
Im confused
thanks in advance

The area of a triangle can be found by using the formula A = 1/2 * base * height, where the base is the length of one side of the triangle and the height is the perpendicular distance from that side to the opposite vertex.
The coordinates of a triangle can be represented by three points, each with an x and y value. In the given example, the coordinates are (-1, 2), (-1, 1), and (2, -1).
The base and height of a triangle can be found by measuring the length of one side and the perpendicular distance from that side to the opposite vertex. Alternatively, if the coordinates of the vertices are known, the base and height can be calculated using the distance formula.
To find the area of a triangle when given coordinates, you can use the formula A = 1/2 * base * height. First, determine the length of one side of the triangle using the distance formula, then find the perpendicular distance from that side to the opposite vertex. Plug these values into the formula to calculate the area.
Yes, the coordinates of a triangle can be negative. In the given example, two of the vertices have negative coordinates (-1, 2) and (-1, 1). This means that these points are located to the left and below the origin on a coordinate plane.
