The perimeter of a triangle is found by adding the three sides. In this case it would be:
.

.
Notice that the two terms involving have opposite signs. Therefore, they cancel
each other out and the problem reduces to:
.

.
And the two radicals add together to give:
.

.
and that is the perimeter.
.
Hope this helps you to understand the problem a little better.
