A landscaper models the area (in units of square meters) of a rectangular flower bed as: $A\left(x\right)=x^2+5x+6$, where $x$ is a side-length adjustment in units of meters. Factor $A\left(x\right)$ to find expressions for the possible integer side lengths (in units of meters) and write the final results in terms of $x$.

• A. $(x+2)$ meters and $(x+3)$ meters
• B. $(2x+3)$ meters and $(x+1)$ meters
• C. $(x+1)$ meters and $(x+6)$ meters
• D. $(x-2)$ meters and $(x-3)$ meters

Answer: (A)
