I have 4 (x,y) coordinates between which I want place image as example given below.
The whole image must be placed within this area without cropping.

Using this 800x600 balloon:
You can use a "Perspective Distort" like this:
convert balloon.jpg -matte -virtual-pixel transparent \
-distort Perspective '0,0,50,0 0,599,100,599 800,0,750,100 800,600,500,500' result.png
There are basically 4 pairs of points in the parameters,i.e.
Pt1X,Pt1Y,Pt1NewX,Pt1NewY Pt2X,Pt2Y,Pt2NewX,Pt2NewY Pt3X,Pt3Y,Pt3NewX,Pt3NewY Pt4X,Pt4Y,Pt4NewX,Pt4NewY
So the command above moves point 0,0
to 50,0
and moves point 0,599
to 100,599
and so on.
I have labelled each of the points in red and drawn the path along which each one has moved in green.
