Question

A square has a side length of n. Which of the following could be used to represent theperimeter of the square?a.n+nb. n. nc. nnnnd. n + n + n + ne. None of these

Answer 1

`n+n+n+n`

Here, we want an expression that could represent the perimeter of a square

A square has all of its 4 sides equal in length

To find the perimeter, we need to add up these lengths

The length we have here is n for each side

Adding all these together, we have;

`n+n+n+n`
