If its a right angle triangle then its side lengths could be 3, 4 and 5

These dimensions do not form a triangle.
depends on wat kinda triangle
That depends on what the side lengths are. Until the side lengths are known, the triangle can only be classified as a triangle.
The area of any triangle is: 0.5*base*perpendicular height
A triangle with side a: 6, side b: 6, and side c: 6 inches has an area of 15.59 square inches.
If you double them all it will be 4 times the area
If you are only given the side lengths of a scalene triangle, it is impossible for you to find for the area, unless you are given more information... like the height of the triangle for example. If this is a right triangle you would like to find the area of, you can multiply the length of each leg with each other, and then divide that product by 2 to conclude the area of the triangle.

he worked on the formula of area of a triangle if you have all 3 side lengths
No. Angles don't have anything called a side length. However, one can use trigonometry to compute the angles of a triangle based on the side lengths of the triangle (triangles do have side lengths).
