Answer:
$1,110
Step-by-step explanation:
To solve this problem, what we need to do is first find the perimeter of the swimming pool and then multiply each foot by $15. The perimeter of a polygon is the sum of all the side lengths, so the perimeter of the swimming pool is 16 + 25 + 16 + 17 which is 74. Therefore, Shelly will pay 74 * 15 dollars which is $1,110.
Hope this helps :)
