Answer because no one ever does barely

For the first rectangle, the answer is 4n+1.2.

Explanation:

The perimeter is all the side lengths added together.  That means, for this rectangle, the perimeter would be n+n+0.6+n+n+0.6, which can be simplified to 4n+1.2.

For the second rectangle, the answer is 6n+0.2.

Explanation:

Again, the perimeter is all the side lengths added together.  That means, for this rectangle, the perimeter would be n+0.1+2n+n+0.1+2n, which can be simplified to 6n+0.2.
