A plane is an undefined term because:
Let us consider the options.
Option 1: can be named using three non collinear point.
This is not the correct answer because a plane is a flat, two-dimensional surface that extends infinitely far. Therefore, it is undefined because it is a flat surface that extends indefinitely in all directions.
Option 2: is described generally, not using a formal definition.
This is not the correct answer because a plane is a flat, two-dimensional surface that extends infinitely far. Therefore, it is undefined because it is a flat surface that extends indefinitely in all directions.
Option 3: is where other geometric shapes can be constructed.
This is not the correct answer because a plane is a flat, two-dimensional surface that extends infinitely far. Therefore, it is undefined because it is a flat surface that extends indefinitely in all directions.
Option 4: is a flat surface that extends indefinitely in all directions.
This is the correct answer as plane is a flat surface that extends indefinitely in all directions.
Therefore, option 4 is the correct answer.

Answer:
Area in square kilometers equals 
Area in hectares equals 1212.6 hectares
Step-by-step explanation:
We know that area of rectangle is length times the breadth.
Using the given values we have

Thus he bought land of area 
We know that 1 hectare =
Thus 12.126
= 12.126/0.01 hectares
Area in hectares equals 1212.6 hectares
