Igure abcd has vertices a(−3, 2), b(2, 2), c(2, −4), and d(−3, −2). what is the area of figure abcd? 5 square units 20 square units 25 square units 40 square units.

It would be B I hope it’s right hope this helps

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
