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

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

Explanation:

{2 + 2w = l

{94 = 2w + 2l

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

94 = 2w + 4 + 4w

94 = 4 + 6w

- 4 - 4

_________

`\displaystyle (90)/(6) = (6w)/(6)`

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