A little over

#### Explanation:

The perimeter is going to be equal to the sum of the lengths of the sides, which can be found by using the distance formula;

Plugging in the points for the first two vertices, we get;

For the second two;

And for the last pair;

So the sum of the three sides is **roughly**;

You can get a more accurate decimal approximation by using a calculator to evaluate the square root values above instead of approximating them.
