Answer from: Quest
solution:
→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.
that is, number of columns of a= number of rows of b.
so, size of matrix , c= a b is , if a = (m × n)matrix
b= (n × p)matrix
then a b = [ (m × n)matrix] ×[ (n × p)matrix ]
→→c= a b= [m × p ] matrix
→→size of product a b will be equal to = number of rows of a × number of columns of b
