Given that vectors form a triangle such that Find p, q, r, s such that area of a triangle is where and [CBSE 2016]

Given: and


Substituting the values of the given vectors in



Comparing both sides, we get


p = s + 3; q = 4; r = 2


Formula: area of triangle =






(s + 11) (s - 5) = 0


s = 11 or s = 5


therefore p = - 8 or p = 8
