---------------------------------------- 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 ------------------------------------------------------------
