Question

if A+B = C where B and C are matrices of order 5×5 Then order of A is:​

Answer 1

Concept:

A matrix is a rectangular array or table with rows and columns of numbers, symbols, or expressions that are used to represent a mathematical object or an attribute of one.

Given:

A+B = C, B, and C are matrices of order 5×5

To find:

The order of A.

Solution:

A matrix is a rectangular array or table with rows and columns of numbers, symbols, or expressions that are used to represent a mathematical object or an attribute of one.

It is given that A+B = C and B, and C are matrices of order 5×5

So, the order of B is $m*n=5*5$

and the order of C is $n*p=5*5$

So, the order of B and C is $m*p=5*5$

Then the order of A will be

$A= C- B\\A= 5*5$

∴The order of A is $5*5$
