(20+30)+3=53
( 20 + 30 ) + 3 = 53
(20×30)+3=603
( 20 × 30 ) + 3 = 603
(20×30)+(20+3)=623
( 20 × 30 ) + ( 20 + 3 ) = 623
(20×30)+(20×3)=660
20 × 30 + 20 × 3 = 660

To correctly use the area model to find \(20 \times 33\), we can break down \(33\) into \(30 + 3\). Using the distributive property, we can express it as follows:
\[
20 \times (30 + 3) = (20 \times 30) + (20 \times 3)
\]
Calculating each part:
1. \(20 \times 30 = 600\)
2. \(20 \times 3 = 60\)
Therefore, we add these two results together:
\[
600 + 60 = 660
\]
So the correct choice that uses the area model to find \(20 \times 33\) is:
**(20×30)+(20×3)=660**
\[
20 \times (30 + 3) = (20 \times 30) + (20 \times 3)
\]
Calculating each part:
1. \(20 \times 30 = 600\)
2. \(20 \times 3 = 60\)
Therefore, we add these two results together:
\[
600 + 60 = 660
\]
So the correct choice that uses the area model to find \(20 \times 33\) is:
**(20×30)+(20×3)=660**
