I haven't learned this yet but I think the other guy deserves brainliest :)

Step-by-step explanation:

If I could put any answer, I think he would be correct

Have a great day!! :)

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

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
