No
Use Pythagoras' Law. In other words, check whether 62 + 92 = 112 (11 is the largest side). If the equation is correct, then it is a right triangle. If not, it isn't.
If you mean dimensions of 11, 60 and 61 then yes they will form a right angle triangle.
No.
55A = ab/2

No.
A right triangle with legs of 7 and 11 units has a hypotenuse of: 13.04 units.
In a right triangle with a hypotenuse of 11 and one leg of 8, the other leg is: 7.55
An scalene triangle.
um.... yes
It can be but need not be.
55A = ab/2
The formula for the area of a triangle is (base x height)/2. Since we're dealing with a right triangle, we can say that the base and height are 10 and 11 units long, respectively. Therefore, the are is (10 x 11)/2 or 55 units squared.
9, 4, and 11 are three dimensionless numbers. Yes, they can represent the lengths of the sides of a triangle. You can take three straight sticks, cut them to lengths of 9, 4, and 11 inches, then lay them down on a table so that the ends hook up and they form a triangle.
