Think of the background image as a sheet of graph paper with the origin (0,0) in the bottom left corner.
The numbers in put-image
specify a point on that graph paper, where the center of the top image should be placed.
The width of the rectangle is 300 and the height is 200. The definitions for dot
and background
are:
dot = circle(50, "solid", "red")
background = rectangle(300, 200, "outline", "black")
Estimate: What coordinates for the dot
would create each of the following images?
A |

put-image(dot, , background) |
put-image(dot, , background) |
