Calculating Garden Fence Perimeter

Maria is measuring the length of a garden to create a new fence. She finds that the garden is 12.75 meters long and 8.50 meters wide. She decides to put a fence around the entire garden. What is the total length of the fence she needs to buy, expressed in meters?

To find the total length of the fence, calculate the perimeter of the rectangular garden using the formula:

$P = 2(l + w)$

where $P$ is the perimeter, $l$ is the length, and $w$ is the width of the garden.
