----(1)
Now AB is given by distance of point A from x axis which will be given by its y - coordinate. So
Similarly BC is the distance of point A from y axis (horizontal distance ) and that will be given by x coordinate of A. So
Plug these values in equation (1)
To divide fractions we flip (reciprocal ) bottom fraction and multiply it to top fraction as shown
Now 2 in top and bottom cancels out so we are left with
so thats the final answer for
