Mr. Lang bought a hat and a pair of gloves for each of his 12 grandchildren. The table lists the cost of each item. Write two equivalent expressions to represent the total amount of money Mr. Lang spent on his grandchildren.

a² + b²= c²

24² + 7² = c²

c= 25

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

i dont understand the question? ?
