An artist needs to paint a mural on a wall to fit the wal the mural needs to be 12 feet high the mural must also be painted so that it looks exactly the same as it does on the sample picture. Which is 8 inches high and 5 inches wide in other words the dimensions of the painting mural must be Proportionate To those of the picture how wide should the mural be

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 answer is (-4,-4)

hope this ! : d
