Question

The perimeter of a rectangle shown below 23 feet what is the missing side length

Answer 1

`n = 7(1)/(4)`

Explanation:

See attachment for complete question.

From the attachment, we have:

`Length = 4(1)/(4)ft`

`Width = n`

`Perimeter = 23fr`

Required

Determine n

Perimeter is calculated as:

`Perimeter = 2(Length + Width)`

Substitute in values

`23 = 2(4(1)/(4) + n)`

Convert to decimal

`23 = 2(4.25 + n)`

Open Bracket

`23 = 8.5 + 2n`

Collect Like Terms

`2n = 23 - 8.5`

`2n = 14.5`

`n = 14.5/2`

`n = 7.25`

`n = 7(1)/(4)`
