Step-by-step Solution
To determine which equation cannot be used to represent the area model, we need to analyze each option in the context of the area model, which typically involves multiplication and division related to area calculations.
(A) \( 42 \times ? = 4,326 \)
This equation is valid in the area model, as it represents finding the missing dimension (height or width) when the area (4,326) and one dimension (42) are known.
(B) \( 42 + 4,326 = ? \)
This equation does not represent an area model. It is an addition equation and does not relate to the concept of area, which involves multiplication or division.
(C) \( 4,326 \div ? = 42 \)
This equation is valid in the area model, as it represents finding the missing dimension when the area (4,326) and one dimension (42) are known.
(D) \( 4,326 \div 42 = ? \)
This equation is also valid in the area model, as it represents calculating one dimension when the area (4,326) and the other dimension (42) are known.
Based on this analysis, the equation that cannot be used to represent the area model is:
**(B) \( 42 + 4,326 = ? \)**
Quick Answer
The equation that cannot be used to represent the area model is (B) \( 42 + 4,326 = ? \).
