Use a area model to find the product 28 time 32

The answer is 896.

Step-by-step explanation: There are several ways to answer this. If you multiply both the 28 and the 32  you get the final answer 896 quickly.

However there are different ways to get the answer that aren't as quick as this one.

First we multiply.

30*20=600

Then we continue multiplying.

8*30=240

20*2=40

8*2=16

Then we add all the values up starting with the hundreds

600+240=840.

40+16=56

Finally we add both of the values up and we get our answer 840+56=896.

A=896 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
