- 310
- 311
- 312
- 313
Hint:
The area model is a rectangular diagram or model used for multiplication and division problems, in which the factors or the quotient and divisor define the length and width of the rectangle.
The correct answer is: 312
write the hundreds ,tens and ones place digits on same side of the rectangles and find the area of corresponding blocks and add the area to find the product
The product = 200 +100 +12 = 312
Therefore, 156 x 2 = 312.
