you multiply all numbers you see. If triangle you multiply all numbers then divide it by three
if the triangle has one right angle in it
Sure, that is exactly what the triangle inequality tells us!
It is a right angle triangle and its largest angle is 90 degrees
If it's not a right angled triangle and you don't have any of the angles but have the values of all three sides, then you need to use something called the Cosine Rule.
By definition, the hypotenuse is the side opposite the right angle in a right angled triangle. Therefore, a hypotenuse does not exist as one of the three sides in a non-right angled triangle.

Yes it is. A normal, 3:4:5 triangle has a right angle, three different angles, and three different sides. There should be more for you to find.
if the triangle has one right angle in it
-- Find the length of one side. -- Find the length of another side. -- Find the length of the remaining side. -- Add the three numbers. -- Their sum is the perimeter of the scalene triangle.

Find the lengths of the sides, and add up the three numbers.

Surely you know how to find the third side of a right triangle, when you know the lengths of the other two. Find it, and then add up the lengths of the three sides to get the perimeter.
If it's not a right angled triangle and you don't have any of the angles but have the values of all three sides, then you need to use something called the Cosine Rule.
To find the area of a triangle, you have to multiply the base of the triangle and the height of the triangle, then divide the product of those numbers by two.
