At least 4 points are required to draw a rectangle.
A rectangle has 4 sides and 4 corners, so at least 4 points are needed to define those corners.

The number of points required may vary depending on the software or tool used to draw the rectangle.
Answering how to calculate new coordinates of a scaled rectangle and providing a program for it.
To calculate new coordinates, multiply the original coordinates by the scaling factor
Scaling factor can be calculated by dividing the new length/breadth by the original length/breadth
Program can take input of original coordinates, scaling factor, and output new coordinates
Example: Original coordinates: (0,0), (0,5), (5,5), (...
