1. **Stating the problem:** We have an area model with tiles arranged in 3 rows and 5 columns representing algebraic terms. The first two rows have 3 blue squares labeled $x^2$ and 2 green rectangles labeled $x$. The last row has 3 green rectangles labeled $x$ and 2 yellow squares labeled 1. We want to express the total area algebraically and verify the factorizations given: $(2x + 2)(x + 1)$, $(3x + 2)(2x + 1)$, $(2x + 2)(2x + 1)$, and $(3x + 2)(x + 1)$.
2. **Understanding the model:**
- Each $x^2$ tile represents an area of $x^2$.
- Each $x$ tile represents an area of $x$.
- Each 1 tile represents an area of 1.
3. **Calculate total area by summing tiles:**
- Number of $x^2$ tiles: $3$ columns $\times$ $2$ rows $= 6$ tiles, so total $6x^2$.
- Number of $x$ tiles: $2$ columns $\times$ $2$ rows $= 4$ tiles in first two rows plus $3$ tiles in last row, total $4 + 3 = 7x$.
- Number of 1 tiles: $2$ tiles in last row, total $2$.
So total area is:
$$6x^2 + 7x + 2$$
4. **Check factorizations:**
We want to factor $6x^2 + 7x + 2$.
Try $(2x + 1)(3x + 2)$:
$$
(2x + 1)(3x + 2) = 2x \times 3x + 2x \times 2 + 1 \times 3x + 1 \times 2 = 6x^2 + 4x + 3x + 2 = 6x^2 + 7x + 2
$$
This matches the total area.
5. **Verify other given factorizations:**
- $(2x + 2)(x + 1) = 2(x + 1)(x + 1) = 2(x + 1)^2 = 2(x^2 + 2x + 1) = 2x^2 + 4x + 2$ which is not equal to $6x^2 + 7x + 2$.
- $(3x + 2)(2x + 1)$ is the same as $(2x + 1)(3x + 2)$ above, so it matches.
- $(2x + 2)(2x + 1) = 2(x + 1)(2x + 1) = 2(2x^2 + x + 2x + 1) = 2(2x^2 + 3x + 1) = 4x^2 + 6x + 2$ which is not equal to $6x^2 + 7x + 2$.
- $(3x + 2)(x + 1) = 3x^2 + 3x + 2x + 2 = 3x^2 + 5x + 2$ which is not equal to $6x^2 + 7x + 2$.
6. **Conclusion:** The correct factorization of the total area $6x^2 + 7x + 2$ is:
$$
(2x + 1)(3x + 2)
$$
**Final answer:** $(2x + 1)(3x + 2)$
