A rectangle is reduced by a scale factor of One-fourth. A large rectangle has a length of 16 and width of 12. A smaller rectangle has length of 4 and width of 3.Which choices show the ratio of the area of the smaller rectangle to the area of the larger rectangle? Select three options. a. 4 / 16 b. 4 / 16 squaredc. 12 / 192d. 4 squared / 12 squared e. 3 / 12 squared

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
