Referring to the figure, the perimeter of a rectangle is the sum of
the lengths of its four sides. Find the perimeter of the rectangle
shown below when x = 2 ft.

The answer to your question is before substitution 8x + 2

                                                    after substitution   18 ft

Step-by-step explanation:

Data

Length of the base = 3x + 1

Length of the height = x

x = 2 ft

Formula

Perimeter of a rectangle = 2(base) + 2(height)

Substitution

Perimeter of a rectangle = 2(3x + 1) + 2(x)

Simplification

Perimeter of a rectangle = 6x + 2 + 2x

Perimeter of a rectangle = 8x + 2

Substitution of x

Perimeter of a rectangle = 8(2) + 2

Simplification

Perimeter of a rectangle = 16 + 2

                                         = 18 ft
