Measure it or use trigonometry if the 'included' angle is given.
It is: perimeter minus hypotenus+base = height Area = 0.5*base*height
Knowing only the angles of a triangle does not provide enough information to determine its perimeter. You must know the length of at least one side.
That depends on what type of triangle is if the side given is equal to the perimeter divided by 3 then it is an equilateral triangle.
If you know the lengths of 2 sides and the included angle then use: Area of a triangle = 1/2*a*b*sinC

A right angle triangle fits the dimensions given
One can't. The angle between those is needed.

The lengths of two sides are not enough to determine the perimeter of a triangle: Either the third side or else the angle between the two given sides is also needed. If two of the sides are 10m and 25m, then the third side can be anything between 15m and 35m, and the perimeter can be anything between 45m and 70m.
you can fine the perimeter
If you have the length of each of the three sides of a triangle, you can find the perimeter of (the distance around) the triangle by adding the length of the sides. Their sum will be the perimeter of this geometric shape.
You cannot. For a given area, an equilateral triangle will have the smallest perimeter but that perimeter can be increased - without limit - without increasing the area.
The dimensions given would not form a triangle and so no perimeter is possible
