WebLet's evaluate the determinant by expanding along the 3 rd column. Notice that this differs in the area of the triangle only in sign. The reason for this is because of the order the points were chosen in. If the points were chosen to be points 1, 2, and 3 in a different order, then the determinant would change only in sign. grand solutions warren ohioWebThe area of a rectangle is base times height, so the bounding rectangle has area = 8 ( 6 ) = 48.
