Answer 1

To determine the amount of fencing needed to enclose the pool area, you will need to add 15 feet to both sides of both dimensions to find the new dimensions that will need enclosed.

28 feet + 15 feet + 15 feet =  58 feet

23 feet + 15 feet + 15 feet = 53 feet

The fence will need to be 2 x 58 + 2 x 53 or 222 feet long for the 53 feet by 58 feet area.
