Question

The length of a rectangle is 5cm more than width. Find expression fo the perimeter of the rectangle in terms of the w

Answer 1

Perimeter
`=4w+10`

Explanation:

Let
`w` = width of the rectangle.

From the information "length of a rectangle is 5cm more than width", we can write:

Length =
`w+5`

- - - -

Perimeter
`= 2l+2w` (formula for the perimeter of a rectangle)

`=2(w+5)+2w`

`=2w+10 + 2w`

`=4w+10`

∴ The expression of the perimeter of the rectangle in terms of
`w` is
`4w+10`.

Hope this helps :)
