A rectangular pool 20 meters wide and 60 meters long is surrounded
by a walkway of uniform width. If the total area of the walkway is 516 square
meters, how wide, in meters, is the walkway?
(a) 43 (b) 4.3
(c) 3 (d) 3.5

• 3 mtrs.
  
  Area of 20x60 mtr pool = 20*60=1200 sq mtrs
  area of rectangle including walkway = 1716 = 26*66
  
  so width of walkway = 6/2= 3 mtrs

  here is direct formula for solving this
  area of path=2w(l+b+2w)
  put the value and get answer
  same formula for when the path is made inside the rectange is
  area of path=2w(l+b-2w)
