John wants to build a fence around his pool. The pool is 22 feet long by 23 feet wide. The fence is to be 15 feet from the edge of the pool. What are the outside dimensions of the area surrounding woool? How many feet of fencing will John need?
To find the outside dimensions of the area surrounding the pool, we need to add 15 feet on each side of the length and width of the pool.
Length: 22 feet + 15 feet + 15 feet = 52 feet
Width: 23 feet + 15 feet + 15 feet = 53 feet
So the outside dimensions of the area surrounding the pool are 52 feet by 53 feet.
To find out how many feet of fencing John will need, we need to calculate the perimeter of this area.
Perimeter: 2(52 feet) + 2(53 feet) = 104 feet + 106 feet = 210 feet
Therefore, John will need 210 feet of fencing to build a fence around his pool.
