Find the Perimeter rectangle (7/18)(7/9)

 $\begin{array}{r} l = & \frac{7}{18} \\ w = & \frac{7}{9} \end{array}$

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

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

Substitute the values of the length $l = \frac{7}{18}$ and width $w = \frac{7}{9}$ into the formula for the perimeter of a rectangle.

$2 \cdot \frac{7}{18} + 2 \cdot \frac{7}{9}$
