To calculate the perimeter of the rectangle, we need to identify the length and width based on the information given.

  1. Length of the rectangle: This is given as \(2x\).
  2. Width of the rectangle: This is given as \(4x + 3\).

The formula for the perimeter \(P\) of a rectangle is given by:

\[ P = 2 \times (\text{Length} + \text{Width}) \]

Now, substituting the values for length and width:

\[ P = 2 \times (2x + (4x + 3)) \]

Simplifying the expression inside the parentheses:

\[ P = 2 \times (2x + 4x + 3) = 2 \times (6x + 3) \]

Now, distribute the 2:

\[ P = 12x + 6 \]

Thus, the perimeter of the rectangle, simplified, is:

\[ \text{The perimeter of the rectangle is } 12x + 6. \]

In summary:

  • Length of the rectangle = \(2x\)
  • Width of the rectangle = \(4x + 3\)
  • The perimeter of the rectangle is = \(12x + 6\)
