----------------------------------------
Define x:
----------------------------------------
Let x be the length of the pool.

Length of the pool and its border = x + 1 + 1
Length of the pool and its border = x + 2

----------------------------------------
Given area = 361 ft², find x:
----------------------------------------
(x+2)² = 361
x+ 2 = √361
x + 2 = 19
x = 19 - 2
x = 17

----------------------------------------
Find Length of the pool:
----------------------------------------
Length of the pool = x = 17 feet

----------------------------------------
Find Area of the pool:
----------------------------------------
Area = 17 x 17 
Area = 289 ft²

------------------------------------------------------------
Answer: Area of the pool = 289 ft²
------------------------------------------------------------

What is the ratio of hot chips to total chips?

Answer:

189 chips

Step-by-step explanation:

Most sources I found online say there is about 9 servings in one bag of hot chips. The back of your bag says that 1 serving is 21 chips. So if we do some basic math, 21 x 9, that means the total amount of the chips inside the bag are around 189 chips!
