Question

The pool at your campsite measures 8 meters by 20 meters. It is surrounded by a path of uniform width, as shown in the figure. The area of the pool and the path combined is 540square meters.

What is the width of the path?

Answer 1

540 - 8(20) = 540- 160 = 380 square meters = area of the path

380 = 2(8x) + 2(20+2x) =20x +40

20x = 340

x = 17 meters = path's width
