The rectangular pool is 45 feet x 18 feet. The fence needs to be 5 ft away from the edges of the pool or a 5 ft border. How many feet of fencing would you need? The area is 810ft

The length of fencing is 146 feet.

(1)

Where:

- Width of the pool, measured in feet.

- Length of the pool, measured in feet.

- Width of the border, measured in feet.

If we know that , and , then the length needed of fencing is:

The length of fencing is 146 feet.
