Answer:
44334
Step-by-step explanation:
The given expression is
[tex]821\times 54[/tex]
We need to find the product of 821 and 54 using area model.
Write each number as the sum of place values.
[tex]821=800+20+1[/tex]
[tex]54=50+4[/tex]
So, the given expression can be written as
[tex](800+20+1)(50+4)[/tex]
[tex]800(50+4)+20(50+4)+1(50+4)[/tex]
[tex]800(50)+800(4)+20(50)+20(4)+50+4[/tex]
[tex]40000+3200+1000+80+50+4[/tex]
[tex]44334[/tex]
Therefore, the value of given expression is 44334.
