Question 1194635
A resort's enormous rectangular pool is 500 meters wide and 250 meters long. A contractor is hired to construct a brick walkway around the pool with an area of 1504 m^2?. 
What are the roots of the working equation?
==============
No "working equation" is given.
If you want to find the width of the walkway:
----
Pool area = 250*500 = 125000 sq meters
x = width of walkway
Area of pool and walkway = 125000+1504 = 126504
(250+x)*(500+x) = 126504
x^2 + 750x + 125000 = 125604
x^2 + 750x - 1504 = 0
x = 2 meters added to length and width
---> walkway is 1 meter wide
