Find the values of k if area of triangle is 4 sq. units and vertices are (i) (k, 0) (4, 0), (0, 2) (ii) (–2, 0), (0, 4), (0, k)  

Answer:

(i) Since the area of a triangle having vertices (k, 0), (4, 0) and (0, 2) is 4 sq. units, we have                                      (ii) Since the area of a triangle having vertices (?2, 0), (0, 4), and (0, k) is 4 sq. units, we have                                                                                            k = 0
