Final answer:
The perimeter of a rectangular field with dimensions (2x + 1) and (x² + 3x + 4) is given by the expression 2x² + 10x + 10.
Step-by-step explanation:
To find the perimeter of a rectangular field with dimensions (2x + 1) and (x2 + 3x + 4), we need to use the formula for the perimeter of a rectangle, P = 2(l + w), where l is the length and w is the width. In this case, the length (l) is (2x + 1) and the width (w) is (x2 + 3x + 4).
Using the given dimensions, the perimeter can be calculated as follows:
This expression represents the perimeter of the rectangular field in terms of x.
