Question

The perimeter of a rectangular pool is more than 62 meters, and the width is at least 10 meters less than the length. Which system of inequalities represents the possible length in meters, l, and the possible width in meters, w, of the pool?

Answer 1

`2(l+w)>62`

`w\geq l-10`

Explanation:

The perimeter
`p` of the rectangular pool with width
`w` and length
`l` is

`p=2w+2l`

`p=2(w+l)`.

We are told that this perimeter is more than 62 meters; therefore, we have the inequality

`2(l+w)> 62`

We are also told that width has to be at least 10 meters less than the length; therefore we have

`w\geq l-10`

Thus the inequalities describing this situation are

`2(l+w)>62`

`w\geq l-10`

Answer 2

the answer would be d i just got it right
