#### Answer

Equal matrices have the same order and the same corresponding elements.

#### Work Step by Step

Consider two matrices A and B.
$A=\left[ {{a}_{ij}} \right]$ and $B=\left[ {{b}_{ij}} \right]$ are said to be equal if and only if both matrices have the same order and A element is equivalent to every corresponding element of B; that is, ${{a}_{ij}}={{b}_{ij}}$ for all i and j.
The order of the matrix means the number of rows and columns in the matrix.
Example:
Consider two matrices $\left[ \begin{matrix}
k & l \\
m & n \\
\end{matrix} \right]$ and $\left[ \begin{matrix}
k & l \\
m & n \\
\end{matrix} \right]$
The above matrices are said to be equal as both matrices are of the order $2\times 2$ and ${{a}_{ij}}={{b}_{ij}}$ for $1\le i\le 2$, $1\le j\le 2$.
