Answer:

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
