Question

if the area of quadrilateral whose angular points taken in order
are (1,2) (-5,6) (7,-4) and (h,-2) be zero, show that h=3

Sahil Jamwal · Answer

i am guessing that this could be proven using the formulae for
finding the area of triangle which u learnt in class 10 as draw the
quad divide it through the diagonal into 2 triangle find thier area
separately then add them and put it =0[given in qustion provided by
u] and then finding corresponding value of h
