To determine

To fill: The blank in the statement “A matrix that has the same number of rows and column is called a(n) matrix”.

Answer to Problem 1AYU

The complete statement is “A matrix that has the same number of rows and column is called a square matrix”.

Explanation of Solution

Given information:

The statement “A matrix that has the same number of rows and column is called a(n) matrix”.

Consider the provided statement “A matrix that has the same number of rows and column is called a(n) matrix”.

In a matrix elements written horizontal form a part of row and elements written in the vertical form a part of column.

When number of rows and column are same it is called square matrix.

For example: $\left(\begin{array}{cc}1& 2\\ 3& 4\end{array}\right)$ is a square matrix of order $2\times 2$ .

Thus, the complete statement is “A matrix that has the same number of rows and column is called a square matrix”.
