Question

The four vertices of a quadrilateral are (1,2), (-5,6) ,(7,-4) and (K, -2) taken in order. If the area of quadrilateral is 0,find the value of k

Answer 1

well according to me answer is 31/3 or 1.33

Answer 2

above question is wrong because for area to become zero All Four Points should be collinear but here first three points (1,2) (-5,6) (7,-4) are not collinear show area of this quadrilateral can never be zero
