How can i find Find the area of the shape: 2.75 m 10 m. Which one you think is the correct answer? 1- 25.5 cm
2- 13.75 cm
3- 27.5 cm
4- 37.5 cm

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

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

its line 2 i just added the rest or else it wouldn't let me answer
