Question

bright pools is building a rectangular pool at a new house. The perimeter of the pool has to be 94 feet and the length has to be 2 feet more than twice the width. What will be the length and width of the pool?​

Answer 1

Answer:

$\displaystyle 15\:feet\:wide \\ 32\:feet\:long$

Step-by-step explanation:

{2 + 2w = l

{94 = 2w + 2l

94 = 2w + 2[2 + 2w]

94 = 2w + 4 + 4w

94 = 4 + 6w

- 4 - 4

_________

$\displaystyle \frac{90}{6} = \frac{6w}{6}$

$\displaystyle 15 = w$[Plug this back into both equations above to get the length of 32 feet]; $\displaystyle 32 = l$
