 $\begin{array}{r} l = & 73 π \\ w = & π \end{array}$

Step 1

The perimeter of a rectangle is equal to the sum of all sides of the rectangle.

$l e n g t h + l e n g t h + w i d t h + w i d t h = 2 \cdot (l e n g t h) + 2 \cdot (w i d t h)$

Step 2

Substitute the values of the length $l = 73$ and width $w = π$ into the formula for the perimeter of a rectangle.

$2 \cdot 73 + 2 \cdot π$

Step 3

Multiply $2$ by $73$ .

$146 + 2 π π$

Step 4

The result can be shown in multiple forms.

Exact Form:

$146 + 2 π π$

Decimal Form:

$165.73920880 \dots$
