This is a bit of algebra.. you do not know either side so the width you will label x and the length you will label x +8. we know that if you add all 4 sides, you will have 256 feet. x + x + (x+8) + (x+8)=256 4x+16=256, Subtract 16 from both sides and you have 4x=240. divide by 4 on both sides and you get. x=60.. That makes the width = 60ft and the length = 68ft

Answer:
no, it is good for 2 weeks (almost 3)
Step-by-step explanation:
The volume of the pool is ...
V = LWH
V = (20 m)(8 m)(1.8 m) = 288 m³
Then the amount of chlorine powder needed for 1 week is ...
(300 g/(50 m³)) × (288 m³) = 1728 g
A box of 5000 g holds enough chlorine for ...
(5000 g)/(1728 g/treatment) = 2.89 treatments
A box of chlorine powder is enough for 2 weeks, not 4.
