Calculating the Perimeter of a Rectangular Garden

A rectangular garden has a length of 15 meters and a width of 10 meters. The owner wants to install a fence around the entire garden. To find out how much fencing is needed, the owner needs to calculate the perimeter of the garden.

Recall that the formula for the perimeter $$P$$ of a rectangle is given by:

$$P = 2 imes (length + width)$$

Using the dimensions given above, what is the total length of the fencing required?
