Find the area of the triangle determined by the points P. Q, and R. Find a unit vector perpendicular to plane P Q R . P ( - 1, 1, - 2 ), Q ( - 2.0.1), R ( 0 .- 2 .- 1 ) The area of the triangle is (Type an exact answer, using radicals as needed) Choose the unit vector perpendicular to plane PQR 1/ 2 (i + j) 1/ 6 (2i - j + 5) ½ 19 (7i - 11j + k) 1/ 6 (i + 2j + 5)
