: A circle has a mass of 3 grams and a square has a mass of 2 grams. Which is the mass of a triangle? А. 9 grams 5 7 5 grams В. C. 3 grams р, 11 grams​

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

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.
