The Hill family and the Gonzales family each used their sprinklers last summer. The Hill family's sprinkler was used for 35 hours. The Gonzales family's sprinkler was used for 20 hours. There was a combined total output of 1850L of water. What was the water output rate for each sprinkler if the sum of the two rates was 70L per hour?

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
