Answer

width of the path= 6 ft

Work Step by Step

Since we are given that perimeter of a pool and the surrounding path = 248 ft Formula to calculate the perimeter of a pool and the surrounding path is : Perimeter= 2( Length + Width) or, $P= 2(l+w)$ Thus, $248= 2 (40+2x+60+2x)$ or, $248=2(100+4x)$ or, $248=200+8x$ Thus, $x=6$ ft Hence, width of the path= 6 ft
