If the points A (

Answer :

Area of triangle with vertices A (x1, y1), B (x2, y2), C (x3, y3) is given by,

(x1 (y2 – y3) + x2 (y3 – y1) + x3 (y1 – y2))

Area (ΔABD) =

= = 12 sq. units

Now, with AB as the base and h as the height of the ΔABD,

Area (ΔABD) =

Distance between two points is given by,


AB =

Area (ΔABD) =

12 =

h =

h = units
