Aballroom in a hotel has the shape shown. the manager needs to determine how much carpet is needed to recarpet this area. all angles are right angles. what is the area of the ballroom?
question 3 options:
42 sq yds
72 sq yds
82 sq yds
100 sq yds

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
