Question

anonymous · Answer

$$ (15 + x)(10 + x) = 250sq yards $$

anonymous · Answer

$$x^2 + 25x + 150 = 250 $$

anonymous · Answer

$$x^2 + 25x - 100 = 0  $$

anonymous · Answer

Using quadratic formula to solve you get 3.5078 and - 28.5

Therefore the total width of the deck on each side of the length and width of the pool is 3.5078 yards.
