Answer:

The perimeter of the rectangle is 10 + 2x.

Explanation:

The formula for the perimeter of a rectangle is 2(l + w) where l = length and w = width because you add up the length of all the sides.

So we can plug in our givens into the formula and simplify:

2(5 + x)

So the perimeter is: 10 + 2x

Notice that we cannot simplify the expression further because there is an unknown (the length).
