The weight (v) of an object on venus varies directly as its weight (e) on earth. a person weighing 120 lb on earth would weigh 106 lb on venus. how much would a person weighing 180 lb on earth weigh on venus?

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

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48
