Question

The perimeter of a square is at the most 22 feet . Let n represent the length of one side of the sqaure . Write an inequality that represent the situation Of the length 2.5 ft , 4.8 ft, 5.2 ft, 5.8 ft, 6 ft, which could be the side length of the square?

Answer 1

The inequality is `4n <=22`

The possible side lengths are
`2.5` ft
`4.8` ft
`5.2` ft

Explanation:

The perimeter is the sum of all four sides.

Therefore, the total of the four sides (`n`) must be
`"less"  "than" or "equal"  "to"`  `22` `"feet"`

`4n <=22`

`color(white)(.........................)` . . . . . . . . . . . . .

The perimeter total can't be greater than `22` feet, so each side `n` must be no greater than `5.5` feet
`22 -: 4 = 5.5`

Of the given choices, all the lengths (`n`) that are less than `5.5` could be the side length of the square:

`2.5` ft
`4.8` ft
`5.2` ft
