Two sides of a triangle have lengths 7 and 16. what must be true about the length of the third side ? . [a] less than 23. [b] less than 7. [c] less than 9. [d] less than 17

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

a: 1/6, j: 1/4
