A rectangular pool 20 meter wide and 60 meter long is surrounded by a walkway of uniform width. If the total area of the walkway is 516 square meter, how wide, in meter, is the walkway?

Let x be the width of the walkway.
The dimensions of teh rectangle formed by the pool and walkway are (60 + 2x) and (20 + 2x)
Area of rectangle formed by pool and walkway = 1200 + 516 = 1716 m2
(60 + 2x)(20 + 2x) = 1716
Solving this we get x = 3 m as x cann not be negative.
