<u>Column Vector</u>
Vectors are matrices having only one column or one row. A vector having only one column is called a column vector, and a vector having only one row is called a row vector.
It's required to find the vector AB as a column vector, and we are given the coordinates of A=(6,4) and B=(2,7).
The vector directed from A to B is found by subtracting its corresponding coordinates:


Now we express the vector as a one-column matrix as follows:

Given:
A rectangular lot measures 160 m by 240 m.
To find:
The area in hectare.
Solution:
We know that, the area of a rectangle is

Using this formula the area of the rectangular lot measures 160 m by 240 m is


Therefore, the area of the rectangular lot is 38400 square units.
