length= x+5 width= 3x+1
Write an expression for the perimeter of this shape and simplify your answer.

Answer 1

4x+12

Explanation:

Assuming the shape is a rectangle with

length=x+5 units and width=3x+1 units.

The perimeter is given by:

`p = 2(l + w)`

We substitute the expression for the length and width to get:

`p = 2(x + 5 + 3x + 1)`

We simplify within the parenthesis to get:

`p = 2(4x + 6)`

We now expand to get:

`p = 8x + 12`

The expression for the perimeter is 4x+12
